As the core component of computer system, CPU plays an important role in computer system. Computer jam is often caused by excessive CPU occupation. How to solve the problem of high CPU occupation? The following is the solution to the excessive CPU occupation of the computer I sorted out for you. I hope it will be useful to you!
1. Turn off the redundant functions of anti-virus software
Although anti-virus software is very good for computers, the negative effect is not small. Computers without anti-virus software are always worrying, but computers with anti-virus software are not reassuring.
Here is a simple example. Ruixing antivirus software will be enabled by default in this machine: vulnerability attack monitoring, memory monitoring, web page monitoring, file monitoring, boot area monitoring, email sending monitoring, email receiving monitoring, and registry monitoring. This means that a lot of memory has been occupied before you run other programs. In addition, you are a user with very little memory, It is likely to run other programs that occupy too much space, and the system will be overwhelmed.
If you run many applications at the same time, please close the unused program window in the taskbar, then open the "rising anti-virus software" interface and switch to the "security" tab. Disable the monitoring functions that are not used temporarily. For example, we plan to browse the website now. Just turn on the web page monitoring, and turn off all other monitoring functions first to save system resources.
2. Carry out anti-virus suppression and occupy resources
In order to seek personal interests, some webmasters took great pains to force everyone to browse their website by means of pop-up advertising virus. What's more, it will pop up a pile of garbage sites from time to time, and won't stop until your CPU is 100%. This virus invades the computer and takes up a lot of resources.
Once the above problems occur, please immediately open the "run" dialog box and enter the command "taskkill / im ieexplorer.exe / F" in its text. At this time, use taskkill to forcibly end all processes in ie, and then run the anti-virus software in this machine to completely kill the virus of the system.
Reduce the resources occupied by BT downloading. Although BT downloading resources is fast, it also occupies a lot of system resources. If the network state is not good, using BT downloading is easy to crash the system. However, we can effectively reduce the resources occupied by BT process by adjusting its priority.
After running BT download, press and hold "Ctrl + Del + Alt" to open the task manager, then switch to the "process" tab, find and right-click BT process in the editing area, and select "set priority" → "lower than standard" in the pop-up shortcut menu to solve the problem of excessive resource consumption of BT download.
3. Close too many startup items in the background
Generally, the situation of pretending to be dead when starting up is basically caused when the user enters the windows desktop, and its CPU utilization rate is as high as 100%. The main reason for this problem is that the system loads too many startup programs, resulting in CPU overload.
Usually, the normal Windows environment is nothing more than loading in the startup program. The system startup program, anti-virus startup program, QQ startup program, and other application programs do not consume much CPU resources at all. So in this case, most of them are viruses in your system, which lead to the fake death of the machine.
The solution to this situation is to keep tapping F8 to enter the system security mode when starting the computer, then open the "run" dialog box, enter the "msconfig" command, and enter the system configuration utility interface.
Then switch to the "startup" tab, check the suspicious "startup item" check box, click the "OK" button, restart and enter the normal Windows environment, and the system will disappear.
1. Trojan horse and virus:
Well, they are the representatives we often meet. This kind of thing can be done easily. For example, there are many worms that multiply rapidly inside the computer, which will cause the CPU occupation to rise too high. For this kind of problem, we should first think of anti-virus software. Normally, we should kill virus in the safe mode, because the killing is relatively thorough. And anti-virus software should be updated frequently, so as to ensure the anti-virus effect and new viruses.
2. Large scale games or programs:
Sometimes the high CPU running rate is caused by some large programs, such as large games with high CPU. There are two normal reasons. The first is that the written programs do not meet the requirements, resulting in the high CPU running rate. This situation is relatively uncommon, because normal games are tested. The second is that the configuration of the computer can't keep up. There is no solution. Either the game is not played, or the configuration of the computer is improved.
3. Computer anti-virus software:
At present, many anti-virus software are installed with real-time monitoring. Although it is to ensure that the computer is more secure, it also increases the burden of the computer, especially for computers with lower configuration, which can no longer install anti-virus software. Only try to install some simple anti-virus software, or it will improve the computer configuration.
4. Disk fragmentation:
Sometimes, the software of the computer will be installed or uninstalled. When the files are installed and uninstalled, the data arrangement in the hard disk will be very scattered or intermittent, which slows down the speed of the computer when searching, resulting in a large amount of CPU use. Therefore, we should always clean up the garbage of the system, and clean up the disk fragments after cleaning.
5. Driver incompatibility:
If the driver is not compatible, it will lead to an increase in CPU utilization. When using the computer, some people will update the driver to the latest. We should first see whether the operating system is compatible with the latest version of the driver. The latest is not necessarily the best. When updating, first check whether the updated version is compatible with the operating system. If updating the driver, it is recommended to use the driver officially released or certified by Microsoft, and the version and model should be adjusted first.
The host does not power on and the CPU does not heat up
We know that when the computer is in normal use, the CPU, graphics card and some components will heat up. When the computer cannot be started, you will find that some components, such as the CPU, do not heat up. In this case, we can first determine that the CPU is not working. We can troubleshoot this kind of computer through the following aspects.
Troubleshooting methods / steps for such computers:
1. CPU damage. CPU damage is generally caused by the power supply of the main board exceeding the voltage borne by the CPU. In this case, it is recommended to remove the CPU and find a good main board for testing. If it is determined that the CPU has been damaged, there must be a problem with the main board. At this time, the motherboard and CPU need to be replaced together.
2. The damage of the mainboard is generally caused by the power supply of the mainboard not meeting the working conditions of the CPU. In this case, it is best to find a mainboard detection card and check the specific fault code. If there is no mainboard detection card, you need to find a professional to repair it.
3. The computer screen is black due to the BIOS setting error. In this case, you need to find the jumper to clear the BIOS on the motherboard and clear the BIOS discharge to restore the default setting.
4. BIOS failure. The data in the BIOS chip is lost, resulting in the black screen of the motherboard and unable to start. In this case, the computer troubleshooting needs to brush the BIOS again for repair.
5. Power failure. Power supply is the energy source of the whole system. Power failure will also cause the whole machine to fail to work normally, which can be eliminated by replacement method.
Computer failure phenomenon 2. When the computer opens one or two programs for more than 80 to 90 degrees, there will be a crash or automatic shutdown.
In the absence of virus interference, for this kind of computer troubleshooting, we can try to use two methods.
Generally speaking, the maximum temperature of the computer CPU should not exceed 85 degrees. It is best to control the temperature below 75 degrees, which is considered safe. If the temperature exceeds 80 degrees, it is easy to cause computer failures such as crash or automatic shutdown, which belongs to poor heat dissipation of the computer.
For the troubleshooting of computer caused by poor heat dissipation, we can achieve the cooling effect by cleaning the fan and applying thermal conductive silicone grease. The former can only significantly improve the heat dissipation capacity of CPU to a certain extent, which can be done with a small hand.
The latter is more professional. The correct method is to apply a thin layer on the surface of the CPU chip, which can basically cover the chip. Coating too much is not conducive to heat conduction. Moreover, silica gel is easy to absorb dust, silica gel and dust, and only by applying thermal conductive silicone grease can all the heat of CPU be transferred to the radiator to ensure that the processor works within the normal temperature.
