Key knowledge: most of the time, we choose to reinstall the driver after the driver has a problem, but you won't think that some faults are caused by the driver. The driver is a foundation for us to use the operating system. Without it, we can't hear the sound, see the pictures and get on the Internet. What if the driver fails? We often choose to reinstall the driver, but some faults may not be caused by the driver at all. The following small series will tell you some common driver fault analysis. Basic knowledge: how to identify the problem symbols of device manager in Windows operating system, device manager is a tool for managing computer hardware devices. We can use device manager to view the hardware devices installed in the computer, set device properties, install or update drivers, disable or uninstall devices, which can be said to be very powerful. Right click & ldquo; on the desktop; My computer & rdquo;, Open & ldquo; Properties & rdquo; Window, switch to & ldquo; Hardware & rdquo; Options page, and then click & ldquo; Device manager & rdquo; Button to enter the window, where all the hardware devices installed in the local computer are displayed, such as optical storage device, CPU, hard disk, display, graphics card, network card, modem, etc. Here, the author introduces some problem symbols in the device manager to my friends.
1. The Red Cross can be seen in the window above & ldquo; IEEE 1394 bus master controller; And & ldquo; PCMCIA card & rdquo; The hardware device in the shows a red cross, which indicates that the device has been disabled. In fact, this is because the author's laptop does not often use 1394 device and PCMCIA card. Considering saving system resources and improving startup speed, these devices are disabled. Solution: right click the device and select & ldquo; from the shortcut menu; Enable & rdquo; Just order.
2. Yellow question mark or exclamation mark if a yellow question mark or exclamation mark is displayed in front of a device, the former indicates that the hardware is not recognized by the operating system; The latter refers to that the hardware has no driver installed or the driver is installed incorrectly. Solution: first, we can right-click the hardware device and select & ldquo; Uninstall & rdquo; Command, and then restart the system if it is windows_ P operating system, which will automatically identify the hardware and install the driver in most cases. However, in some cases, you may need to insert a driver disk. Please follow the prompts.
I. sound card
1. Windows prompts that the hardware driver is not found. Such failures are generally due to the failure to complete normally when loading the driver for the first time, or in config Sys, automatic batch file autoe_ EC. BAT、DosSTART. A sound card driver has been running in the bat file. For this, you can delete a driver file running inside. Of course, you can also delete the three files mentioned above to solve the fault. If there are no files in the above three files and the driver cannot be installed, you need to modify the registry and click & ldquo; Start & rdquo; Menu & mdash& mdash;& ldquo; Run & rdquo;, Enter & ldquo; in the dialog box; regedit” Press enter to delete the registry key related to the sound card (for example, if the sound card model is als300, click & ldquo; edit & rdquo; & mdash; & mdash; & ldquo; find & rdquo; of the registry key, enter als300, and then delete the found byte, press F3 to continue to find the next one, and then delete the found option one by one). Another easiest way is to insert the sound card into another slot, find the new device again, and load its driver to solve the problem. Although the second method is simple, we should follow the principle of software before hardware to solve the fault. Only before the first method, users had better export the registry and back it up in case of accidents.
2. System failure caused by obsolete sound card driver: an old computer has recently installed windows_ P system, the installation process is very smooth. Windows for_ P system is a big memory consumer. A second-hand 128MB SDRAM memory is added to make the system run more smoothly. But soon the problem came: the system crashed frequently during operation, especially when chatting on the Internet and QQ. Analysis and solution: because the system installation is very smooth, is it the fault caused by the installed second-hand memory? So first remove the memory and restart it. The fault remains the same. In order to eliminate the conflict between the application software and the system, reinstall the system, but the fault remains the same. Considering that the aging of power supply and network card failure can also cause similar phenomena, the fault was not eliminated after being replaced respectively. Now the weather is very hot. Is it the crash caused by poor CPU heat dissipation? It is detected that the CPU temperature does not exceed 46 ℃ in BIOS, which eliminates the suspicion of poor CPU heat dissipation. Finally, the problem seems to focus on the motherboard and hard disk. The hard disk is a newly upgraded Seagate 20GB. There should be no problem. The system test also proves this. Is it because the driver of the motherboard is too old, and the new windows_ P system incompatible? I tried to find a new driver update on the motherboard on the Internet, but I didn't find it, but I accidentally found the on-board AC & lsquo; 97 sound card's new driver, although the sound card has been working normally, you can download it and try it first. Delete the old sound card driver, install a new driver, and restart. The fault is solved. It turned out that the sound card driver was old, resulting in and windows_ System failure caused by poor compatibility of P.
3. After the driver is loaded, the sound card is silent. First, check whether the wiring between the sound card and the speaker is correct. The signal line of the speaker should be connected to the speaker or SPK port of the sound card. If the wiring is correct, enter the multimedia option of the control panel to check whether there is a sound device inside. If there is a device, it indicates that the sound card driver is loaded normally, otherwise the driver is not installed successfully or there is a device conflict. If there is a device conflict, it can be solved according to the following method:
1) replace the sound card slot (in my experience, it is better to insert the sound card, modem and other expansion cards into slots 2, 3, 4 and 5, because slot 1 will generally conflict with the graphics card).
2) enter the sound card resource setting option to see whether its resources can be changed to a non conflicting address or interrupt.
3) enter the reserved resources project to see whether the resources used by the sound card can be reserved for other devices.
4) check whether there is jumper on the sound card and whether the interrupt port can be changed.
5) turn off unnecessary interrupt resource occupation, such as ACPI function, USB port, infrared and other devices.
6) upgrade the sound card driver.
7) load the motherboard driver and try again. In the multimedia options mentioned above, if there is a sound device, but the sound card is silent, you can enter the volume adjustment menu of the sound card to see whether it is muted. There is another special case. Some sound cards must be installed with setup in the driver to make them in coufig and autoe first_ In EC and bat files, establish some files that drive the sound card, which can occur normally under windows (such as 4dwave sound card).
4、AC‘ 97 sound card drive failure and Troubleshooting Analysis: there are & ldquo; representative sounds in the desktop taskbar; Small horn & rdquo;, Normal volume control can also be carried out by clicking, but the speaker cannot make sound (since the speaker has been normal before, the possibility of speaker failure can be ruled out). Author opens & ldquo; Device manager;, See & ldquo; Sound, video and game controllers & rdquo; & ldquo; in; Soundma_ Integrated Digital Audio” There is no yellow exclamation mark in & ldquo; Soundma_ Integrated Digital Audio” & ldquo; Properties & rdquo; There is also no interruption conflict in the resource item, & ldquo; General & rdquo; This item shows that this device is currently working normally. By asking a friend, I learned that since these machines do not have optical drives, the driver reads the sound card driver folder \ sound \ ADI \ soundma in the shared optical drive on the server_\ 188_ \Win95, and copy it to the local hard disk, and then execute the setup in the folder e_ E) installation. Compared with the motherboard, it is found that this motherboard does not use 188_ Series of soft sound cards, but via's own AC & lsquo; 97 sound card. It seems that the speaker doesn't sound is caused by the wrong installation of the sound card driver. Troubleshooting: the author is at & ldquo; Device manager & rdquo; Delete & ldquo; Soundma_ Integrated Digital Audio” Item, restart the machine, put the drive CD attached to the motherboard into the CD-ROM drive, the CD-ROM will run automatically, and & ldquo; will be displayed in the second item; VIA AC97 PCI Sound Drivers”， Click to enter the sound card driver installation interface, and then the system prompts: the onboard sound card has been disabled, please reset it in BIOS. Enter BIOS and find & ldquo; Integrated Peripheral Setup” & ldquo; in; Onboard AC97 Audio” One item, set to & ldquo; Enabled”， It seems that Win98 is lying about military intelligence. Enter the system again and open & ldquo; in the device manager; Soundma_ Integrated Digital Adio” & ldquo; Properties & rdquo; Item, select & ldquo; Driver & rdquo; & ldquo; Upgrade driver & rdquo;, In & ldquo; Upgrade device driver wizard;, Select & ldquo; Displays a list of all drivers in the specified location so that you can select the desired driver & rdquo; from the list;, Click & ldquo; Next & rdquo;, Select & ldquo; Install & rdquo; from floppy disk;, Browse the driver location: \ sound \ via \ MVP4 \ win98se, and finally find & ldquo; VIA AV97 Audio Controller ? WDM?& rdquo;， Click & ldquo; Next & rdquo; After, the system warns that the selected driver is not designed for the selected hardware and may not work properly & hellip& hellip; Select & ldquo; Yes & rdquo;, After installation, restart the machine, and the familiar Win98 startup sound finally came out of the speaker. Enter & ldquo; Device manager;, In & ldquo; Sound, video and game controllers & rdquo; In, the & ldquo; VIA AC97 Audio Controller ? WDM?& rdquo; This is the real via AC & lsquo; 97 sound equipment. Using the same method, all machines are smoothly installed with the correct drive, and the fault is removed.
5、Windows _ P conflicts with the driver of the innovative sound card. This situation may be windows_ P caused by the problem of the driver itself. Because innovation did not release the sound card in windows_ P, but due to windows_ P is developed from Windows 2000, so it can be replaced by the driver of the sound card on Windows 2000, which can always be solved.
6. Fault phenomenon caused by wrong installation of sound card driver: reinstall win_ After P system, when the program of TV card is opened for the first time to watch TV programs, the sound card can pronounce normally, but after switching to other channels, the TV programs will have no sound. After exiting, you can't turn on the TV player again. You can only restart the computer to have sound when watching TV programs, but you can continue to repeat the above fault as soon as you change the program channel. And this fault only occurs when using the TV card. Before and after the fault occurs, play other multimedia files, and the sound card can pronounce normally. Troubleshooting process: because the TV card is connected to the line input port of the sound card through an audio line, there can be sound when watching TV programs, so I first unplug this audio connection line and directly connect the speaker to the audio output port of the TV card. As a result, the sound is normal, that is, there is a problem with the sound output of the TV card. However, after replacing the connection line, the problem still exists. So I decided that there was something wrong with the sound card of the computer. Since the computer plays other multimedia files and the sound card can sound normally after watching TV programs with silent failure, I suspect that there is a conflict between the sound card driver and the TV card driver, but in the process of uninstalling the sound card driver, the computer actually restarts automatically and cannot enter the system in safe mode. After disabling the sound card driver in the BIOS, I can uninstall the original sound card driver. After uninstalling the sound card driver, I reopen the sound card in the BIOS settings. After entering the computer, let win_ P automatically looks for the driver of the sound card on the motherboard driver disk. The system quickly finds out the location of the driver and automatically installs the sound card driver, but the fault still exists. Later, reinstalling the TV card driver can not solve the problem, because the computer can watch TV programs normally before reinstalling the operating system. Is the TV card incompatible with the sound card integrated on the motherboard? With this question, I looked through the instructions of the TV card and the motherboard, but the instructions stated that they were compatible with win_ P system. The sound card model written in the motherboard manual has attracted my attention, because the sound card model written in the motherboard manual is cmi9739. Just now, when the system automatically installed the sound card driver, the driver of alc100 sound card was installed. In order to determine the model of the sound card, I opened the chassis and found that the sound card chip of the motherboard was indeed cmi9739 After that, I uninstall the original sound card driver, and then reinstall the driver of cmi9739 sound card. The fault is solved. Generally speaking, if the wrong sound card driver is installed, the computer cannot pronounce normally, but later I tried on other computers and found that after installing ALC series sound card driver, the motherboard of integrated vti612a and cmi9739 chips can pronounce normally, but it will be incompatible with TV card. And often in win_ In the process of installing the driver of the P operating system, everyone is used to only clicking the next step, ignoring the selection of the driver automatically found by the system. Therefore, it is suggested that when installing the sound card driver, you'd better first look at the manual of the motherboard, or check the model of the sound card chip on the motherboard.
II. Graphics card
1. Problem of graphics card driver failure Q: after reinstalling the operating system, it is found in & ldquo; Hardware device manager & rdquo; Inside & ldquo; Other equipment & rdquo; Inside & ldquo; There is a yellow question mark in front of the video controller (VGA compatible). Students said that this phenomenon is caused by the lack of driver installed on the graphics card, but my motherboard and graphics card are integrated, and I don't know the model of the integrated graphics card. I used Everest software to test the graphics card model, but I couldn't detect it. Later, I found the instruction manual of the motherboard, which said that via k8m400 chipset was adopted. Where can I download the graphics card driver of the chipset? A: This is a classic problem. Some hardware is too old to recognize the motherboard, but if you know the motherboard chipset model, the driver will not be a problem.
2. There is no display at startup. Such faults are generally caused by poor contact between the graphics card and the motherboard or problems in the motherboard slot. If there are some memory slots on the main board, note that the first memory slot should be inserted on the main board. There is no display fault when starting up due to the reason of graphics card. Generally, a long and two short beeps will be sent out after starting up (for award BIOS graphics card).
3. The flower screen is displayed and the handwriting cannot be seen clearly. This kind of fault is generally caused by the display or graphics card does not support high resolution. You can switch the startup mode to safe mode when the screen is displayed, then enter the display setting under Windows 98, and click & ldquo; in the 16 color state; Apply & rdquo& ldquo; OK & rdquo; Button. Restart, delete the graphics card driver under the normal mode of Windows 98 system, and restart the computer. You can also edit system in a pure DOS environment without entering the safe mode INI file, display Change DRV = pnpdrver to display drv=vga. After DRV, save and exit, and then update the driver in windows. The color display is abnormal, and such faults generally have the following reasons:
1)。 Poor contact between display card and display signal line
2)。 The display itself is faulty
3)。 In some software, the color is abnormal when running. It is generally common in old computers. There is an option to check the color in BIOS. Just turn it on
4)。 The graphics card is damaged; 5)。 The display is magnetized. This kind of phenomenon is generally caused by being too close to the object with magnetic properties. After magnetization, it may also cause the deflection of the display screen.
4. In case of crash, such faults are usually seen in the incompatibility between the main board and the graphics card or the poor contact between the main board and the graphics card; The incompatibility between the graphics card and other expansion cards will also cause crash.
5. Abnormal dots or patterns appear on the screen. Such faults are generally caused by problems in the graphics memory of the graphics card or poor contact between the graphics card and the motherboard. It is necessary to clean the golden finger of the graphics card or replace the graphics card.
6. The graphics card driver is lost. When the graphics card driver is loaded, the driver is automatically lost after running for a period of time. This kind of fault is generally due to the poor quality of the graphics card or the incompatibility between the graphics card and the motherboard, resulting in the high temperature of the graphics card, resulting in the unstable operation of the system or crash. At this time, only the graphics card can be replaced. In addition, there is a special case. The graphics card driver can be loaded before, but the crash occurs when entering windows after the graphics card driver is loaded. You can replace other models of graphics cards. After loading its driver, insert the old graphics card to solve it. If this kind of failure cannot be solved, it indicates that the registry is faulty. Restore the registry or reinstall the operating system
7. Restart failure caused by graphics card driver. This may be after installing windows_ After P, instead of using its own graphics card driver, I reinstalled the graphics card driver on the hard disk. Because this driver is dedicated to Windows 2000, I think Windows 2000 and windows_ P is a 32-bit operating system based on NT kernel. And some articles have said that when some graphics cards can't find windows_ When using the special driver of Windows 2000 / NT, I can try to replace it with Windows 2000 / NT. Although I can run most programs and games after using it, the above faults are finally caused by some small differences in the driver. It seems that installing the graphics card driver should also suit the remedy to the case!
8. After installing the graphics card and modem driver, the sound card driver crashes, which is caused by the conflict between modem and graphics card. The sound card should be installed before installing the modem driver to work properly. If the problem still cannot be solved, you can first open the chassis, unplug the built-in modem from the motherboard, then install the Windows98 operating system, and then install the drivers of graphics card and sound card. Then exit the operating system and shut down, plug the modem into the motherboard and restart the computer. The system will prompt to find new hardware, install the modem driver according to the prompt, and finally restart the computer.
9. After the graphics card driver is installed normally, the resolution can only be adjusted to 640_ 480, why? This may be caused by the incorrect installation of the driver for the display in the windows 2000 operating system. The solution steps are:
(1) right click the desktop and select & ldquo; from the pop-up shortcut menu; Properties & rdquo; Options, in the pop-up & ldquo; Properties & rdquo; & ldquo; of the dialog box; Settings & rdquo; Tab, click & ldquo; Advanced & rdquo; Button.
(2) in & ldquo; Monitor & rdquo; Click & ldquo; in the tab; Properties & rdquo; Button in the pop-up dialog box; Driver & rdquo; Click & ldquo; in the tab; Update driver & rdquo; Button. In the Wizard dialog box that appears, follow the prompts to step into installing the driver.
10. The most common cause of failure of driver installation due to hardware conflict is that the driver cannot drive the hardware normally after installation due to interrupt, DMA, I / O address and memory address conflict between the hardware. This kind of conflict mainly exists in Windows98 and windowsme systems, WIN2000 and win_ P usually does not appear. The symptom is that the driver installation is normal, but the hardware just can't work normally. The Red Cross and yellow exclamation mark appear in the resource manager: this kind of fault is mainly due to two different hardware using the same IRQ interrupt number, DMA request, memory address or I / O address, such as the conflict between the serial mouse using com2 port and the built-in modem, the network card and printer Such failures can occur in graphics card conflicts. Solving such problems requires a gradual elimination process:
Step 1: enter the BIOS first, and the & ldquo; Resources Controlled By Auto” Change to & ldquo; Manual”， Let the computer automatically allocate these resources.
Step 2: if it still can't be solved, try to replace the expansion card with the PCI slot, close the unused devices in the system and release more available resources.
Step 3: if the problem still cannot be solved, you need to manually specify different resources for the hardware, or try to upgrade the motherboard BIOS and hardware driver to solve this kind of fault. Ask the driver database to help solve the problem. Sometimes, after installing or updating the driver of the specified hardware in Windows 98 / me, it doesn't work correctly. Even if you try to install the driver again, it still doesn't work. When you're at a loss, maybe rebuilding the windows driver database can solve this problem. What is & ldquo; Windows driver database;? Windows provides a driver information database (called hardware information database in Windows Me), which includes all drivers of the current system. These databases are included in drvdata.com of windows \ inf Bin and drvid_ In the bin file. When the driver is updated or changed, the information in the driver information database will also be changed. However, Windows does not check that the driver is installed correctly. Therefore, if you have the problems mentioned above, you can rebuild the driver information database and remove any information that may cause mismatch files when installing drivers. Let's take a look at how to rebuild the driver information database:
Step 1: before completing the update, be sure to prepare the hardware driver, because after deleting the device, windows will prompt to install the device when restarting.
Step 2: enter windows security mode and press & ldquo; Win+Break” Key combination to open & ldquo; System properties & rdquo;, Enter & ldquo; Device manager & rdquo; Tab, delete all items of the faulty equipment from the listed equipment number model, and then close it. If prompted to restart the computer, click & ldquo; No & rdquo;.
Step 3: Click & ldquo; Start & rarr; Find & rdquo;, Then click & ldquo; File or folder & rdquo;, In the name box, type & ldquo; drvdata. bin”， Then click & ldquo; Find & rdquo; now;. Once found, right-click & ldquo; Drvdata. bin”， Select & ldquo; Rename & rdquo;, Rename it & ldquo; Drvdata.___& rdquo;。
Step 4: use the method in step 3 to; Drvid_. bin” Rename to & ldquo; Drvid_.___& rdquo;。
Step 5: restart the system and enter the normal mode. Windows will create the driver information database and prompt to install the default driver of the problem device. Put it into the driver floppy disk of the hardware or specify its storage location in the hard disk, and then install it. After installing the driver, the work is extremely unstable. Because the system automatically installs the driver more compatible with the hardware, or the old version driver is not completely cleared, the hardware does not work or the working state is extremely unstable. This kind of fault is common in Windows98, Windows2000 and windows_ P will appear, and because it is the driver loaded automatically by the system, there will be no obvious error prompt for faults such as interrupt conflict on the surface. Friends who have used intel810 motherboard know that this motherboard has different sound card chipsets because of its low price. Alc101, alc201, sigma 9721, ADI 1881, ess1869, crystal 4239, via AC97 and so on make some novices as big as cattle when installing sound card drivers. These chips are different from each other; Compatibility & rdquo; Better. Therefore, no matter you install any driver, the system will not have an error warning or obvious signs such as interrupt conflict. Everything on the sound card is displayed normally, but it just can't pronounce normally. The wrong driver is deleted normally, but after restarting, the system will automatically & ldquo; Smart & rdquo; The unloaded driver is loaded. Even if the correct driver is installed, the system will still take the driver installed for the first time as the default driver of the sound card, so that some friends have to reinstall the system and install the sound card driver again, so they ask God to worship Buddha. So how can I completely delete unnecessary drivers? Most people will reinstall the driver from the control panel or delete the hardware from the explorer, but this step is not enough. The system does not completely delete the old driver. You have to perform the following operations. Windows 98 / me: you also need to delete the relevant inf files in the C: \ windows \ inf folder (you can use the search function to directly use the hardware name as the keyword), and the system will not find the inf installation file when loading the driver and give up the installation. Window 2000/_ P: In addition to deleting the corresponding INF file in the C: \ WinNT \ inf folder, you also need to delete the INF file with & ldquo; OEM” Delete the files at the beginning. These files are actually the backup of inf files. If they are not deleted, the system will still load the wrong driver after startup, and the purpose of updating the driver will not be achieved. Faulty installation of imperfect drivers due to the installation of imperfect drivers, missing or damaged system or driver files, and improper setting of hardware related options. Due to the poor compatibility of some hardware, even if none of the above faults exist, there will be problems in the process of use. For typical examples, for example, ALC series sound card, which is most used on intel845 series motherboard, may suddenly lose sound in the game or there is no sound when playing video files. For example, users using nforce2 motherboard have encountered such a situation in Windows 2000 system, When entering the desktop or copying files, the sound card will make a loud sound or play intermittently, and the network will suddenly interrupt the connection for no reason. These situations are caused by the imperfect drivers of the sound card and network card. In case of these situations, we should pay attention to whether the latest driver is released& ldquo; Illegal operation & rdquo; It's all the trouble caused by the driver. The good hardware used in the past, such as modem, scanner and printer, suddenly prompts illegal operation (as shown in the figure below) or random code prompt. Most of these failures are caused by the loss and incompleteness of system or driver files caused by illegal shutdown, virus destruction, misoperation deletion, program confusion, etc. to solve these failures, first thoroughly kill the virus of the system, and then restore the system files to normal, such as using the system file checker under windows (enter & ldquo; SFC & rdquo; in & ldquo; start & rarr; run & rdquo;) Or system restore, and finally reinstall the hardware driver. Generally, it can be solved after three steps. Improper setting of driver related options will lead to abnormal operation of hardware. In addition, improper setting of driver related options will also lead to abnormal operation of hardware, which is different. For example, setting the OpenGL map detail of the graphics card too low will lead to blurred game picture, setting the resolution beyond the bearing capacity of the display will lead to black screen, and assigning invalid IP address and gateway to the network card will lead to network failure, A typical example is a friend who uses ALC series sound card. After installing the driver, the system will automatically install soundma_ It is loaded automatically at startup. Using this software can easily adjust the computer environment and monochrome, but sometimes the sound card suddenly & ldquo; Denaturation & rdquo;, The male voice completely turned into a female voice, unable to do anything. Somehow, it was finally found that it was caused by improper settings. These operations are related to the options provided by the driver. When troubleshooting, you can gradually find the root cause of the problem by carefully looking at the hardware related settings and programs.
III. main board drive
1. The main board drive causes the computer to crash. Recently, the computer that my friend has just assembled often crashes. The fault phenomenon is that when running some graphics and image processing software, the machine crashes every time it is processed and saved, which makes my friend very angry. After reinstalling the operating system for many times, the fault is still not eliminated, and the most important thing is that my friend's computer can't install the scanner normally, It brings great inconvenience to friends' work. Fault analysis and solution: my friend is engaged in decoration design. The purpose of assembling this computer is to design drawings. Therefore, the configuration of the machine is not low. The specific configuration is as follows: Elite 915pe chipset motherboard, seven rainbow 6600 graphics card, Kingston 512M DDR400 memory, Intel 775 pin 64 bit 506 processor (main frequency 2.66G), Seagate cool fish seventh generation 160GB PATA hard disk, Samsung DVD-ROM drive, and Tsinghua Ziguang scanner brand. According to a friend, this computer is an assembly machine. It has been used for about half a year. One of them is relatively stable and has no problem. Once, by chance, after the computer was infected by a virus, my friend reinstalled the operating system, and then the scanner could not be installed normally. In addition, when executing the image processing software (my friend often uses Photoshop) to save, there was often a crash, and it was still the same every time I restarted. The faults were more frequent. During this period, my friend did not overclock any hardware. That is, the computer can run normally without reinstallation, and often crashes after installation, which fully shows that the failure possibility of hardware damage is unlikely, so the author focuses on the software failure. According to friends, it is very easy to crash when running image processing software. The first thing to check is direct_ The version of, or whether there is a problem, does not support the machine well. Open direct_ Check that its version is 8.1 (my friend installed the windows 2000 operating system), so_ The software was upgraded to version 9.0c, and the image processing software was run again, but the fault remained. Therefore, the author suspected that it could be caused by a friend's accidental shutdown or misoperation. The system lost a file or caused the error of registry data. Therefore, the author switched the computer to dos and used scanreg / restore to restore the registry of the system. The problem remains. The difficulty is that there is a problem with the hardware, so the author opened the chassis, carefully checked the hardware of the computer, focused on the heat dissipation of the machine, and eliminated the hardware faults one by one, but the problem remains. What is the reason? The author calmed down and thought carefully. Suddenly, he thought of the hardware device manager, so he opened & ldquo; Control panel & mdash; System & mdash; Device manager: in the window of the device manager, the author is surprised to find that there are two items marked with yellow exclamation marks (marking yellow exclamation marks indicates that the device has problems and cannot be used), which are & rdquo; PCI Universal Serial Bus“ And & rdquo; PCI BridgePCI Universal serial BUS“， View their & rdquo; Attribute & ldquo;, It was found that the device drivers of these two items were not installed correctly, so the author concluded that the problem was here. It should be noted that PCI bridge is & rdquo; PCI bridge & ldquo;, It is mainly used for the high-speed connection channel between Eide interface and motherboard, so that Eide interface can better support high-speed data transmission mode (i.e. ultra DMA 33), so as to greatly improve the transmission speed of Eide interface (generally, the installer will automatically detect and install the driver of PCI bridge under Windows). Now these two items are marked with yellow exclamation mark, indicating that there must be a problem, And it will affect the performance of the motherboard, resulting in crash. Meanwhile, PCI universal serial bus is a PCI bus device, commonly known as & ldquo; Universal serial bus (USB) & rdquo;, It is to connect the computer with general USB devices such as scanners, digital cameras and printers, so that the computer can obtain more data information from the outside. Now this device is not available, which means that the computer cannot normally obtain information from the USB external device, so the scanner cannot be installed normally. The driver of the motherboard was found and reinstalled after the failure of the motherboard was found. Finally, I asked my friend that after installing window 2000, he directly installed the frequently used software and did not install any motherboard driver. Fault summary: PCI and USB devices should be installed automatically when Windows 2000 is installed. My friend didn't install these two items when installing the system, which indicates that there is a problem with my friend's installation system disk. Therefore, we remind you that after installing the system, you must first install the drivers of hardware devices such as motherboard and graphics card, and check the installation of each hardware device under the device. If there are any problems, they should be solved immediately, and then install various application software to prevent unnecessary trouble caused by incorrect driver installation.
2. After installing the driver patch of MSI motherboard, enter the system blue screen. A computer with MSI 815ept (6337) motherboard. After installing the motherboard inf in the process of Windows 98, restart the computer according to the system requirements. As a result, a blue screen appears in the process of entering windows. What should I do? The solution is: after installing the motherboard driver, restart the computer, enter the safe mode first, scan the C disk once, and then restart the computer. The system will automatically detect the new device and install the corresponding motherboard driver.
3. Windows 2003 fake death uncover the secret and install the motherboard driver carefully. I began to use it shortly after the launch of Windows 2003. I always feel that its stability and speed are very good. Later, because of work needs, I installed multiple operating systems, but I found that there were often false crashes (the mouse didn't respond, and it usually took three or four seconds to return to normal). Once I went to a friend's house to play, he happened to use Windows 2003, and found that there were the same problems as my computer, so I carefully looked at his settings and found that he used via 4in1 motherboard driver, which is the 443 version. After downloading the latest 449sp3 (version supporting Windows 2003) from the Internet, I played the game for a long time, and there was no false crash again. After returning home, I wondered if my windows 2003 would also be a false crash caused by improper installation of the motherboard driver, because I used the amd750 motherboard and did not have a motherboard driver supporting window 2003. Considering that Windows 2003 has the function of return drive, enter the device manager and set & ldquo; IDE ATA / ATAPI Controller & rdquo; & ldquo; AMD-756 PCI Bus Master IDE Controller V1. 36” And & ldquo; System equipment & rdquo; & ldquo; AMD-751 Processor to AGP Controller” Returns the driver. After restart, there is no false crash for no reason, and the computer has been running stably.
4. Related to the mainboard driver, if the mainboard driver is lost, damaged or repeatedly installed, it will cause the operating system boot failure or unstable operation of the operating system. You can turn on & ldquo; Control panel & mdash& mdash; System & mdash& mdash; Device manager & rdquo; Check & ldquo; System equipment & rdquo; Whether the items in the have yellow exclamation marks or question marks. Delete all items marked with yellow exclamation mark or question mark (you can operate in & ldquo; safe mode & rdquo;), reinstall the driver of the motherboard and restart it. For example, the motherboard with Intel Chipset should be installed with & ldquo; Intel Chipset Software Installation Utility” Motherboard driver, motherboard with via chipset needs to install & ldquo; 4 In 1” Drive to achieve better stability and compatibility
IV. network card
1. Phenomenon of slow startup speed after installing the network card driver: restart the computer after installing the network card driver. It is found that the startup speed is much slower than before. Troubleshooting: first, eliminate the errors in the process of installing the driver. Generally speaking, after the network configuration of a single machine, the system starts much slower than before because the system detects the network card once more. This is a normal phenomenon. Also, if you do not specify an IP address for the network card, the operating system will automatically search for an IP address to assign to it at startup, which will take about 10 seconds. Therefore, even if the network card is not used, it is best to assign an IP address to it, or simply set it to off in the BIOS, so as to improve the startup speed. Problem summary: after adding network equipment to a single machine, it is generally slower to start. Of course, if the system starts and stops for a long time, you have to pay attention to inspection. This paper summarizes that the frequency of network card failures in network hardware is still relatively small. To sum up, most of the fault sources are the matching of network card driver and transmission rate (i.e. connectivity soft fault); The usual solution is to uninstall the driver and then reconfigure the network card parameters.
2. Troubleshooting of network card driver. Due to anti-virus, abnormal shutdown and other reasons, the network card driver may be damaged. If the network card driver is damaged, the network card cannot work normally, and the network cannot be pinged, but the network card indicator lights up. At this time, you can use & ldquo; Control panel & rdquo; Medium & ldquo; System & rdquo; & ldquo; Device manager & rdquo; Option to check whether the network card driver is normal. If & ldquo; Network adapter &; The network card icon shown in is marked with a yellow & ldquo& rdquo;， It indicates that the network card driver is abnormal. Reinstall the network card driver to solve the problem.
3. Uninstall the stubborn network card driver. My computer is connected to the network through the school LAN. The network card and sound card are respectively installed on the PCI slot of the host. Because the chassis needs to be replaced, they are all removed and reassembled. I don't remember that the original network card is inserted on the first PCI slot, so I casually install the network card on one of the PCI slots. After entering WIN2000, the system automatically finds my network card, but & ldquo; is added after the original network card name# 2” Sign of. After use, it is found that you cannot access the Internet. Check & ldquo; Online neighbors & rdquo; Attribute. I found that all the IP addresses inside were not set, so I had to set them all again, but I still couldn't surf the Internet. At this time, I began to doubt the name of the network card. Did the original network card not be uninstalled, and there was a & ldquo; Conflict;? Right click & ldquo; My computer & rdquo; Select & ldquo; Attribute & rdquo;, Click & ldquo; Hardware & rarr; Device manager;, Check the network card. But only the network card with # number on the back. Click & ldquo; View & rdquo; & ldquo; in one item; Show or hide devices & rdquo;, There is still no original network card device, so how can we delete it? Is it the only way to open the chassis and change the position of the network card slot? I opened the control panel and suddenly noticed & ldquo; Add / Remove Hardware & rdquo; One item, double-click run, and click & ldquo; Next & rdquo;, Select & ldquo; Uninstall / unplug the device & rdquo;, Click Yes & ldquo; Uninstall the device & rdquo;, The dialog box lists the list of hardware to be uninstalled. Put the following & ldquo; Show or hide devices & rdquo; Tick, hey, I found my original network card name (no #2 sign), remove it! Go back to & ldquo; System properties & rdquo; & ldquo; Device manager & rdquo; Select & ldquo; Operation & rarr; Scan for hardware changes;, There is no # number behind the network card found this time. Finally to & ldquo; Online neighbors & rdquo; According to the original setting steps, reset the IP, gateway, subnet mask and DNS. Open IE and check. OK! Connected. This time, the & ldquo; Fault & rdquo; Give me some experience: if in Win2000/_ Under P, the network card device changes. It is best to uninstall the network card from the device manager first to avoid problems when installing the network card again.
V. other driving faults
1. In the article "handling of unloading fault of Wenjing a210 driver", the handling method of driving fault of Founder Wenjing a210 laser printer is introduced. The author has also encountered this fault. Occasionally, the printer does not print one day. When reinstalling the driver, the system will prompt to uninstall the old driver first, but run the uninstall program and prompt uninst The ISU does not exist, the uninstall is aborted, and the installation cannot proceed. Through groping, another solution was found. Prompt uninst during uninstall ISU does not exist, but if you look at the directory where the print driver is located, you can find uninst ISU this file, I guess it's uninst There is a problem with the ISU file. Take the printer driver CD to another computer for installation. After installation, enter the directory where the driver is located and find uninst ISU this file, compare the two files and find that the sizes of the two files are different. Put the new uninst Copy the ISU file and overwrite the original uninst ISU file, and then run the uninstall program.
2. Troubleshooting the modem driver installation, add new hardware and select the add port. When selecting the driver, an mdm3com was found on the modem driver disk INF file, select it immediately, all the way ne_ t. After completion, you will find that there is an additional COM3 port in the device manager, and it works normally. Start adding modem driver manually, and select the newly installed COM3 when selecting the port, and the road will be smooth in the future. I heard the last dial-up connection; Ziwu Ziwu & rdquo; A loud cry. The printer always has a blue screen when installing the driver. The solution is that the device to be used is occupied. Restart the computer and check that the device is available. This phenomenon is also related to the virus infecting the system or the printer driver is not installed correctly. The solution is as follows:
(1) remove the virus. After power on, enter the BIOS Setup screen and set the boot sequence option in the BIOS features setup menu item to disk a startup. Then insert the anti-virus floppy disk into the floppy drive, restart the computer, and carry out anti-virus operation on the hard disk after normal startup.
(2) reinstall the printer driver. Remove the original printer driver and reinstall the driver.
(3) if the problem still cannot be solved, you can use the Windows 98 installation CD to recover the operating system.
3. There is an error prompt on the screen when running the print driver. This is because some running applications in the system conflict with adobe font download program. The solution is as follows:
(1) when running Adobe font download program, close the status window of the printer. (2) Close applications in the system that will lock the parallel port of the printer, such as font manager.
4. Fault phenomenon of miscellaneous handle drive: Recently, the author added an 80GB hard disk to his favorite machine (the original disk is the master disk and the new disk is the slave disk). Originally, I thought the system performance could be greatly improved. However, after installation, some conventional software such as office is running_ P, not only the startup speed is much slower than before, but also there will be a short-time stop response when running the program, especially in the game. Troubleshooting: since the system runs normally before installing the new hard disk, the cause of the failure should be related to the new hard disk. Therefore, the author began to check the hardware settings changed when installing the hard disk, and checked the hard disk data cable and power cable, but no problem was found. Suddenly, the author found that the parallel port of the computer was idle, which should have been connected to a 25pin game console. When installing the hard disk, the author thought that the wiring was too much, so he pulled out the temporarily useless handle interface and forgot to connect it later. Is it because of this that the above failure occurs? With the idea of trying, the author reconnects the game console to the parallel interface after shutting down, and then turns it on. After entering the system again, everything returns to normal. Connect the new hard disk again, and there is no longer the phenomenon of slow program operation. Fault analysis: after the author's analysis, this should be the fault caused by the joystick driver. The author bought a miscellaneous handle, and the random driver may be imperfect. When the supported hardware is unplugged, the original driver may disrupt the normal operation of the system, resulting in the above failure. In order to verify my idea, the author is in & ldquo; Device manager & rdquo; Uninstall the driver of the game console, and then unplug the handle interface. As expected, the system does not run slowly again. Therefore, the author suggests to choose a well-known brand when purchasing the game console, so that not only the hardware quality can be guaranteed, but also the software development is relatively mature and there will be no inexplicable faults.
