Computer freezes after 20-25 minutes of work?

Question

Iron

Hello, I ran into a problem, after starting the computer, after about 20-25 minutes, the screen completely freezes (I can watch something in the browser, or play a game, it doesn’t matter), while the mouse works, that is, its movements are visible on the screen, however, all applications and commands do not work, checked for viruses, everything is clean, what could be the problem, will reinstalling windows help?

Answer 1

Reinstall your system to rule out a problem with Windows.
Then look for patterns in the hovering (after which, how often, for how long).
I bet on a bad power supply. Check its voltage in the BIOS.

Answer 2

If the hang time is not arbitrary, but strictly at a certain time, then I think that you either have a power plan set for this time, or some program or even a virus can affect it. I heard that apple specifically slowed down old iPhones in order to sell new ones, there was a big scandal and resignations. So there is a conspiracy theory too.

Answer 3

Overheating
Memory
problem Video card (video memory) problem

Answer 4

Refresh firewood for mother

Answer 5

If only the cursor moves after the freeze, it is likely that neither the driver nor the mother nor the vidyuha has anything to do with it.
A moving cursor with a frozen picture on the screen rather indicates a frozen explorer process. If the
ctrl+alt+del combination works, then explorer is definitely frozen .
