Laptop hangs up?

Hi

if I search for something in my browser (for school) then I get a screen freeze and I have to force my laptop to shut down I'm relatively sure that I don't have a virus (says Windows security)

Do a CPU stress test with CPU-Z. Maybe the thermal paste in the laptop has dried up.

I let it run for 6 minutes and everything is fine, even when gaming, everything is ok only for "schoolwork"

Or

Try reinstalling Windows

li

OK. Then it will probably have nothing to do with it. But I would load Avast instead of the built-in Windows security.

fa

Then I have to reinstall all programs

fa

And my internet is pretty bad

Ca

Fan defective?
Runs for about 15 minutes without a fan. Then the PC hangs up.

No, the fan is OK and behaves normally only when I leave it inside in "frozen" mode, the built-in illuminated keyboard becomes dark and the fan becomes as loud as when gaming after about 6 minutes
