1 It was just an accident, and it can be ruled out 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 because of a blue screen! Windows XP itself has a BUG. Its performance is: in the process of shutdown, blue screen appears intermittently, and we can solve this problem by downloading patches! 3. Driving problems. We can find the recently installed drivers, whether there are compatibility problems or restore the system to the final correct operation! If you use an innovative sound card and a blue screen appears during the shutdown, the error code is "0X0A", then please enter the device manager, delete the sound card, refresh and manually install the latest driver with digital signature. 4 Software conflicts lead to a blue screen shutdown. Please make sure to close 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 the virus. Enter the safe mode, completely antivirus! 6 motherboard BIOS is unstable. Uninstall BIOS or upgrade motherboard BIOS! 7 The abnormal shutdown of the computer leads to blue screen failure. 8 memory loss. Most of the memory sticks are oxidized, so replacing them with an eraser can basically be eliminated, and the problem of incompatible memory can be solved by reloading the system! The quality of large-capacity memory is generally uneven, and fake and inferior products are easy to cause blue frequency failure because of poor quality! File pointing error caused by registry corruption leads to blue screen. 10 hardware failure. This can generally be solved by substitution! 1 1 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 is wrong. It is best to scan and repair with disk tools! 13 Too little disk space or too many junk files also seriously affect the computer operation! We should form the 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, some important installed files will be overwritten under the system. 17 check whether the wiring in the chassis is loose and whether the hard disk interface and the memory of the graphics card, network card and sound card are plugged tightly. 18 power supply problem. Due to the unstable voltage of inferior power supply, it is very likely to cause a series of problems such as restarting the blue screen for no reason. The main reason of blue screen caused by power supply problem is voltage instability, which forms some pulse resistances in a series of devices such as graphics cards for a long time. When the computer is turned off, it will find an error, so it will cause a blue screen!

I hope it helps you! thank you
