1) Software first, then hard. Reinstall the operating system, do not install software, patches, drivers, etc. See if there is anything wrong with the boot. 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.

2) Is there anything wrong with the hardware, such as hard disk, memory, graphics card and motherboard? If it is caused by hardware problems, it is recommended to overhaul.

3) What's more, it has something to do with improper operation before you turn it off? For example: playing games, watching videos, operating big things, and using computers for a long time? Or download inappropriate things, the fault will not happen for no reason (if this problem is caused, just pay attention to your computer not being stuck, blue screen, and suddenly shut down, so the boot will not happen)?

If it is caused by 3, as long as you pay attention to your computer is not stuck, not blue screen, not suddenly shut down, boot will not be like this.

Ask me any questions.
