If you don't install drivers, patches, and software step by step, don't install anything that doesn't fit (if you have any questions, please ask me).

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) Whether there is a problem with hardware, such as hard disk, memory, graphics card, motherboard, etc., if it is caused by hardware problems, it is recommended to overhaul it.
