1) is caused by the operation before shutdown:
It takes a long time to play games, watch videos, operate big programs or use computers. At this time, it is very stuck. You should be patient and wait for the computer to recover slowly. Click on every page on the computer and slowly recover. When it returns to normal, turn it off or do other operations. If it still doesn't work, press the on/off key to turn it off. If the computer is turned on for too long, my experience is to restart it every once in a while to release the cache and continue playing.
2) Turn off the blue screen every time:
If you have installed the sogou input method, or have installed the QQ input method and tried to uninstall it, you can also try to uninstall and reinstall the input method (these softwares are the culprit, which is learned from the communication with the finder). If it is not the problem here, see the following method).
Try to uninstall all software, drivers, patches, etc. I downloaded it before the accident. If the uninstalled software is invalid or you don't know what is installed, first soft and then hard, and restore the system. Still can't reinstall the operating system (ask me questions).
3) If the above methods can't be solved, first soft and then hard, reinstall the operating system, and don't install software, patches, drivers, etc. See if there is any problem with the shutdown. Don't install drivers, patches and software step by step, and don't install them if you find them inappropriate.
Please note: if you restore or reinstall the system, when installing drivers, patches, software and other things, you must not install things that affect your accident this time, otherwise it will be futile to restore or reinstall.
4) If it is caused by hardware problems, repair is recommended.
