(1) The blue screen is caused by computer operations:

1. Recall, what operations were performed before the blue screen? Press F8 to enter safe mode, delete, uninstall, and cancel your previous operations.

2. Press F8 to enter safe mode and select "Last Known Good Configuration" or "Normal Startup".

(2) The blue screen is caused by hardware:

1. Replace or add hardware, and hardware incompatibility occurs. Remove the newly added hardware. If the newly added hardware is compatible, a blue screen may occur because the system cannot recognize the newly added hardware. It is recommended to reinstall the system.

2. If the computer is used for a long time, the golden fingers of the memory and graphics card will be oxidized, causing poor contact. Remove the memory and graphics card, wipe the gold finger of the card with an eraser, and then add a small amount of absolute alcohol to the card slot (to clean the oxides in the slot). After a few minutes, blow dry with a hair dryer. , and plug it in again.

3. The hard disk is unstable. This failure is caused by the hard disk being damaged. Repair the bad sectors of the hard disk or replace the hard disk directly.

4. If the keyboard and mouse are faulty, re-plug and unplug the USB.

5. There is a lot of dust in the chassis. Clean the dust (usually once every 3-5 months). And remove the CPU fan, gently wipe off the silicone grease on the U, and then reapply a thin layer of new silicone grease.

6. Overclocking may also cause a blue screen on the computer. If it is overclocked, cancel the overclocking.

7. Restore BIOS settings.

(3) The blue screen is caused by software:

1. Caused by 360 repair. Uninstall 360 or reinstall the system.

2. Caused by vulnerability repair or anti-virus. This failure is caused by improper operation and patch uninstallation.

3. It is caused by software such as Driver Wizard and Driver Life, but such faults are rare. Due to poor compatibility between the system and the graphics card driver (do not pursue new drivers, some new drivers are not suitable for your graphics card), such errors may also occur. It is recommended to replace the appropriate graphics card driver installation.

4. If the computer is infected, use professional anti-virus software to perform full anti-virus, delete the files in the quarantine area, restart the computer, and perform another scan to prevent secondary virus infection.

5. If unstable software is installed, it is recommended to perform a full anti-virus, uninstall the software that caused the problem, and reinstall other versions of the software.

In fact, if the computer has a blue screen, the best solution is: reinstall the system. If you find that the installed system often displays blue screens, you should install it on another system.

If the system is reinstalled after being poisoned, it is recommended that after reinstalling the system, install anti-virus software first, conduct a thorough full scan, and then install other software.

I am happy to answer your question:

You can better analyze it by looking at the blue screen code of your computer

1. There are viruses in the computer (open Computer Manager, then anti-virus and then scan). If a Trojan or virus is found, you should restart it immediately. After restarting the computer, go to "Isolation | Recovery" and completely delete the Trojan and virus!

2. The computer system is interfered with by stubborn viruses, Trojans or worms, or system files are lost (Trojan detection by Computer Manager, open Computer Manager and then scan and kill viruses)

3. The software downloaded on the computer has conflicts and is incompatible (Computer Manager, uninstall the software, find and uninstall, then: Power Clean)! For example: there are duplicate or similar players, there are redundant ones of the same type among anti-virus, browsers, games, and input methods. Uninstall the redundant ones and keep only one!

4. The software needs to be updated (Computer Manager, software upgrade, download, overwrite installation, winrar does not need to be upgraded)

5. There are new vulnerabilities waiting to be installed in the system, (open Computer Manager - Vulnerability Repair - Scan and Repair)

6. The graphics card or memory CPU, or the fan has poor and loose contact or is covered with dust (unplug the eraser)

7. The memory CPU is overheated and the heat dissipation is not good! (Don’t turn it on for too long, shut it down to dissipate heat)

8. There is a bad review plug-in on the computer! (Scan it out and clean it up immediately) or there are too many disk fragments.

9. If it still doesn’t work, it means the system files are lost! Or there is a serious error in the system memory!

10. Try pressing F8 after booting, Enter, Enter, enter safe mode, configure the last time correctly, press and try! Or, enter safe mode, go to the desktop, open Tencent Computer Manager, and do a full anti-virus!

11. When playing a game with a blue screen, it usually means that the system does not support the game! (Change the game version or change to xp system)

12.

Downloaded games, players, input methods, download tools, browsers, drivers, and other programs are unstable! (Use Computer Manager to uninstall and reinstall or upgrade to the latest version)!

I wish the author a smooth work and a happy life! !
