Why does the PC recover itself?

Question

Iron

The computer seems to take on a life of its own. There are no viruses, but sometimes it turns itself off, then the system crashes and does not want to recover from restore points. The monitor constantly goes into economic mode and it is often impossible to even start safe mode. And in the morning the PC always starts up normally, the system is restored, although an error was constantly generated and Windows was not loaded. Also absolutely does not want to install OS from a flash drive. Can't see or crash at the end. What about him?

Answer 1

А почему Вы решили, что на компе нет вирусов?
Может просто Ваш антивирус их не видит.
UPD. Скорее всего так и есть, слишком много проблем для простого глюка системы.

Answer 2

I always said that these computers are controlled by shaitans, here you can’t do without an admin tambourine, just the admin needs to pour something tasty to drink and have something good to eat.
knowledgeable people would take everything apart, test all the components, set up the bios, install the axis that they put constantly checked, and you would live happily

Answer 3

Apparently dispersed or overheated! Is it self-collection or something!
