The first reason: for example, playing too much software, antivirus software and optimization software, such as computer housekeeper, will conflict with each other and cause blue screen. Generally, you only need to uninstall the software with the same function and keep one.
The second reason is that the gold finger surface of memory or graphics card is oxidized, which leads to poor contact between memory and memory slot, and poor contact between graphics card and graphics card slot, which leads to hardware incompatibility, and the resulting blue screen phenomenon is accompanied by error codes.
Solution: You can turn off the power first, open the compartment, pull out the memory stick, rub the golden finger back and forth with an eraser several times, and then insert a memory stick back, and it will be ok. If you have an independent graphics card, you can also handle the graphics card in the above way, but don't change the slot, and then install and restart the computer (take the memory slot as shown below).
The third reason: your system is poisoned, and the virus destroys the operating system, causing the system to fail to start, leading to repeated blue screens, accompanied by blue screen codes. So simply restore or reinstall the system with one key. After finishing the system, install anti-virus software and completely kill virus.
The fourth reason: if the hard disk has bad tracks, it will also cause frequent blue screens, so you should use DiskGenius in PE to check and repair your hard disk. Generally speaking, there will be no problem and there will be no such phenomenon.
The fifth reason is that you reinstall the system, change the format of the disk, or don't go to the system after reinstallation, and the opportunity will appear blue screen. This is mainly due to the blue screen recorded in the main boot area, so it can be handled as follows:
First of all, you should prepare the latest installation CD of GHOST version with PE, whether it is XP or WIN7 (general software stores or computer stores buy 5-8 copies) or prepare a USB flash drive with PE, then press F 12 or DEL to enter the BIOS, set the first startup item as CD-ROM drive (or USB flash drive), put it in (or insert a USB flash drive) and enter the CD-ROM drive. Enter WINPE, find a software called diskgenius, open this software, find your "hard disk", select your hard disk, right click, and a drop-down box will pop up, which reads "Rebuild Master Boot Record (MRB)". Click this "Rebuild Master Boot Record (MRB)" and a dialog box will pop up. Click "Yes". Then restart the computer, your computer can enter the operating system, and 95% can solve the problem.
