1 is only an accident, which can be eliminated by restarting. We can't rule out this possibility, because it exists in probability, and we can't stubbornly think that the computer is faulty just because of a blue screen!

2 there is a BUG in Windows XP itself. Its performance is: in the process of shutdown, blue screen appears intermittently, and we can solve this problem by downloading patches!

3 driver problem. We can find the recently installed drivers, whether there are compatibility problems or restore the system to the last correct operation!

If you are using an innovative sound card, and a blue screen appears during the shutdown process, the error code is "XA", then please enter the device manager, delete the sound card, refresh it, and manually install the latest driver with digital signature.

4 software conflict causes a blue screen of shutdown. Make sure to shut down all running programs before shutting down. If the shutdown blue screen appears repeatedly, please check the compatibility of the recently installed software or reinstall the system, restore the system or delete the recently installed software.

5 infected with virus. Enter safe mode and completely kill virus!

6 the motherboard BIOS is unstable. Discharge BIOS or upgrade motherboard BIOS!

7 blue screen failure caused by abnormal computer shutdown.

8 memory failure. Most of the memory chips are oxidized, which can be basically eliminated by changing the memory slot with an eraser, and the incompatibility of the memory can be solved by reinstalling the system! The quality of bulk memory is generally uneven, and fake and inferior products are easy to cause blue frequency failure because of poor quality!

9 blue screen caused by file pointing error due to registry corruption.

1 hardware failure. This can generally be solved by substitution!

11 hardware resource conflict. Abnormal error caused by conflicting settings of video card or sound card. Solution: Enter "Safe Mode", "Control Panel-System-Equipment Management" and make appropriate adjustments, which can generally be solved!

12 hard disk partition information error. It is best to use disk tools to scan and repair!

13 Too little remaining disk space or too many junk files also seriously affect the computer operation! We should form a good habit of cleaning up the disk garbage regularly!

14 overclocking causes blue screen failure.

15 dust problem. Cleaning the garbage in the cabinet regularly can effectively prevent the crash and blue screen!

16 when upgrading DX, cover the installation some important files under system.

17 check whether the wiring in the chassis is loose, whether the hard disk interface and the memory of the video card, network card and sound card are plugged tightly.

18 power problem. Due to the unstable voltage of inferior power supply, it is very likely to cause a series of problems, such as the phenomenon of restarting the blue screen without reason. The main reason for the blue screen caused by power supply problems is that the voltage is unstable, and some pulse resistors are formed in a series of devices such as graphics cards for a long time. When the computer is turned off, it will find errors, so the blue screen is caused!
