Under normal circumstances, the blue screen is a conflict or incompatibility after the hardware driver or new hardware is added and the driver is installed, and the "last correct configuration" provided by Windows is a shortcut to solve the blue screen car laughter. Reboot the system.

Some of the BSOD is caused by a flaw in Windows itself, so it can be solved by installing the latest system patches and service packs.

If the system can be run, the wrong patch with conflicting closure is played, you can use Tencent PC Manager to "extend the scan", scan immediately, after the scan is completed, it will prompt: which patch, does not need to be repaired. Then, follow the prompt:

Deal with it immediately. When you're done, if you are prompted to "restart your computer", restart your computer immediately and you're good to go.

Switch switch.

Reinstalling the system is the most fundamental, thorough, and hassle-free way to do it. Tinkering, there will be problems here or there, and you will be entangled.
