(1) First of all, understand the situation of the computer before the blue screen occurs and operate it well. If the computer has a blue screen after overclocking the CPU or memory, the blue screen failure is related to overclocking, as long as the frequency returns to normal.

(2) If the computer is turned on abnormally when reading the CD in the CD-ROM drive, the blue screen fault is caused by misoperation. This kind of failure is usually to put the CD back into the CD-ROM drive and then close the tray of the CD-ROM drive.

(3) If the computer has a blue screen when plugging and unplugging the electrical equipment, the blue screen fault is related to plugging and unplugging the electrical equipment, and it can generally be recovered by restarting the computer.

(4) If the computer has a blue screen when using an application software, the blue screen failure may be caused by the application software. Generally, you can uninstall the program software and reinstall it to troubleshoot; If not, there may be something wrong with the program software itself and it cannot be used.

(5) If there is a blue screen after the computer enters the system, there may be many reasons for the blue screen failure, which need to be eliminated step by step. First, use anti-virus software to kill the virus and eliminate the blue screen failure caused by the virus. If the fault is eliminated, it is a blue screen fault caused by the virus.

(6) If it is still the same, restart the computer, and then start the computer in "safe mode". After startup, exit the system and restart to normal mode. If eliminated, it is a blue screen failure caused by a system error.

(7) If the fault is not eliminated, use the backup registry to restore the Windows registry to a normal state. If the fault is eliminated, it is a blue screen fault caused by Windows registry corruption.

(8) If the fault is not eliminated, use the event viewer in Windows system to find the cause of the error. Take Windows2000\\XP system as an example. First, click Control Panel/Administrative Tools/Event Viewer to open the Event Viewer window. In the right window of the Event Viewer window, the system lists the events that use the computer. Then, according to the date and time, focus on the events marked as "error" in "System" and "Application". Then double-click the "Error" event to open the "Event Properties" dialog box of the error event, find the cause of the error, and then make targeted repairs.

(9) Last resort: If it is a win7 system, you can try to reinstall the system. If not, change to xp system. If not, it's probably a hardware problem. Compatibility with hardware is also related to the hardware itself.
