Today, the editor will share with you the relevant knowledge points about the common computer failures and solutions of the xp system. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

1. System downtime

Phenomenon: the desktop is locked, the mouse can not move, even hot start (ALT+CTRL+DEL) is not allowed in serious cases. And then there is the blue screen phenomenon.

Phenomenon analysis: the BUG of the "Windows" system and the compatibility between the software are the cause of the failure, or it may be that the user runs too many large programs at the same time, resulting in process blocking and crash.

Countermeasures: when the machine is divided into two kinds, true and fake, the easiest way to distinguish between the two is to press the Numlock key in the keypad area to observe whether the indicator light has changed. Yes, it's a fake. On the contrary, really. If you can press ALT+CTRL+DEL at the same time to select the program name in the task list that appears and mark the items that do not respond, click end the task. Really, only the cold start. For the blue screen, after pressing the ESC key is invalid, select restart and press the reset key on the chassis panel. The compatibility problem can be solved by uninstalling the "problem" software and updating the motherboard BIOS and related motherboard drivers.

two。 Virus attack

Phenomena: slow operation of the system, crash, illegal operation, flashing hard disk lights, frequent blue screen, and inexplicable system hints.

Phenomenon analysis: virus is essentially a malicious computer program code, virus through a large number of self-replication, while secretly running in the system, occupy system resources, serious damage to software and hardware, such as CIH, hard disk lock and so on.

Countermeasures: as virtue rises one foot, the devil is one foot low, the nemesis of the virus is antivirus software. Once you suspect that your machine is infected with a virus, please restart the system to DOS and run the genuine antivirus software (DOS version) so that you can kill the virus that cannot be killed under "kiss to death". Then boot to the system desktop and run the WINDOWS version of the antivirus software for re-antivirus. On the other hand, some files will be destroyed when the virus breaks out seriously. Just before the outbreak of the virus, we backup the important files to a drive other than disk C, and set the properties of the data files to read-only. At the same time, we should always update the antivirus software virus library, reduce the use of pirated discs, friends who have been online should not download unknown email attachments.

3. Automatic shutdown

Phenomenon: the computer suddenly shuts down or restarts the system automatically during normal operation.

Phenomenon analysis: today's motherboard has a temperature monitoring function for CPU. Once the CPU temperature is too high and exceeds the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the relevant hardware. On the other hand, the power management and virus software in the system will also lead to this phenomenon.

What should be done: if the above sudden shutdown phenomenon continues to occur, first confirm whether the heat dissipation of the CPU is normal. Check whether the fan blade is working properly in the boot box, and then enter the BIOS option to see the fan speed and the working temperature of CPU. If it is found that it is the problem of the fan, carry on the related dedusting maintenance of the fan or replace a better quality fan. If you rule out the hardware, enter the system, cover the installation power management from the "Kiss to death" installation CD, and then thoroughly check and kill the virus. When these factors are eliminated, the cause of the failure may be the aging or damage of the power supply, which can be confirmed by replacing the power supply. If the power supply breaks down, it will be replaced by a new one. It must not be used any more and the hardware will be destroyed.

4. Out of order

Phenomenon: can not enter the system, the typical performance is to pass the post, stop at the startup screen, or display: The disk is error and many other phenomena with English prompts.

Phenomenon analysis: this is a system failure, which can be caused by many reasons, the more common is that the system file is modified, destroyed, or loaded with abnormal command line. In addition, hard disk failure is also one of the reasons.

What to do: first try whether you can enter safe mode, press F8 to boot, and select the third item in the startup menu: Safe model (safe mode). After entering safe mode, you can find the fault through the device manager and the system file checker. No. Can find out the body and then determine whether the del or setting interrupt. You can also reinstall the driver, and the damaged system files can be recovered from the installation files (it is recommended to copy the WINDOWS installation disk to the hard disk in advance). If you can't even enter the safe mode, boot to DOS with a booted CD or floppy disk, first kill virus under DOS and use Dir to check whether the system files in disk C are complete or not. If necessary, you can use the system floppy disk to perform Sys CDir to restore the relevant basic system files. If no files are found on disk C, the system will have to be completely reinstalled.

There are three rules to help you whether the system needs to be reinstalled.

If one of the following three situations occurs in the system, it is time for you to consider reinstalling the system:

The main results are as follows: 1) the running efficiency of the system becomes low, the junk files are full of the hard disk and the scattered distribution is not convenient for centralized cleaning and automatic cleaning.

2) the system makes frequent errors, and the faults are not easy to locate and solve easily.

3) the system cannot be started.
