The computer will inevitably have this and that fault after a long time of use, so what are the most common problems that we can solve by ourselves. The following is the computer common problems and faults I sorted out for you. I hope they are useful to you!
Computer common problems and faults
1. The computer runs too slowly
In addition to the hardware factors, the computer speed is also closely related to the system. First of all, you can insist on whether the disk space is full, especially the C disk of the computer. If it is close to the limit, you need to delete some content to get more space, so it is recommended that the application should not be installed on the C disk as far as possible. In addition, some startup items of the computer system can be reduced to achieve faster startup speed.
2. The computer network speed is too slow
If your network speed is too slow, you might as well log in to such as Speedtest Net to test the network speed. If the speed is really slow, check the router. If it is normal, you can call the broadband provider to inquire whether there is a problem with the network service. If the wired or WiFi network cannot be connected all the time, there may be a problem with the network card hardware. Try downloading and installing the latest driver first. If it still fails, there may be a hardware problem and it needs to be replaced.
3. The computer keeps restarting
The continuous restart of the computer is usually caused by two aspects. One is infected with the virus, so we can enter the safe mode to check and kill the virus. If the situation remains the same, it may be caused by poor heat dissipation of the hardware, so you can clean the computer after all the hardware has been updated normally.
4. Block pop-up advertisements
Many times, when we install software, we will accidentally install some spam plug-ins, which will slow down the computer or pop up advertisements. Through some anti-virus software, we can remove the contents of these spam plug-ins, such as 360 anti-virus software. In addition, you can also shield Trojans or phishing websites by installing such protection software, so as to provide you with a green and safe online environment and ensure the normal operation of your computer.
5. The wireless network cannot be connected
Sometimes, windows can't connect to WiFi wireless network all the time, or the display is limited all the time. We can try to solve the problem through the "troubleshooting" and "automatic detection and repair" functions in the system first. If the problem persists, check the router or PC hardware step by step.
6. Website security certificate
If the prompt "there is a problem with the security certificate of this website" appears frequently when using the browser to surf the Internet, it may be due to the incorrect setting of the system clock. Usually, the CMOS battery of the PC motherboard will keep the clock running. If it fails, you can try to replace the battery.
7. The printer does not work
In addition to ensuring that the printer driver is the latest version and has enough paper and ink, we can try to restart the printer, find the contents in the system tray, check the print queue and ensure that the "printer offline option" is not checked. We must pay attention to these detailed problems.
8. Unable to open email
Usually, if you can't open the attachment of e-mail, it is because the corresponding software, such as PDF file, is not installed on the computer. Therefore, you can install compatible software to correctly identify. In addition, e-mail attachments cannot be opened if they do not have the correct extension.

1. Generally, more than 80% of computer system faults are software faults. At the same time, most software faults are relatively easy to deal with, while most hardware faults are caused by peripherals. Therefore, the analysis and fault finding should be carried out in the order of "software before hardware, external before internal".
2. Common software faults.
A. error prompt: in case of software failure, many errors can be captured by the application software or operating system and give corresponding prompts. Such failures are generally caused by software defects, software conflicts, improper configuration or wrong operation.
B. application software fails to start normally: such failures are generally caused by software conflict, wrong operation, improper configuration or virus.
3. Handling methods of common software faults.
A. use anti-virus software: in case of inexplicable slow down or error of the system or application, scan the whole system with anti-virus software to determine whether the system is poisoned.
B. single application system failure: for single application system failure, the application is generally reinstalled. If you are familiar with the system, you can check the system configuration first and then decide whether to reinstall the system
4. Causes and treatment methods of common hardware faults.
The causes of computer hardware failure are mainly related to the use environment, users' operation habits, natural aging of hardware and poor quality of hardware products. Under normal circumstances, the hardware failure of the system can be eliminated as long as the faulty hardware equipment is found and replaced.
5. When the computer system has a fault, first confirm the fault phenomenon through observation and inspection, then analyze the fault phenomenon, judge the possible cause of the fault of the computer system according to the corresponding relationship between these fault phenomena and possible causes, and then use the troubleshooting method to eliminate the impossible fault causes, so as to gradually determine the fault causes. When the fault causes are determined, Then start the maintenance.
6. The above contents involve relevant computer knowledge. If non professionals suggest to find enough experience before actual operation, some complex computer faults need to be repaired by professional maintenance points and professional maintenance personnel.
