Funny graphic bugs and spontaneous changes in resolution?

I currently have the problem that makes my laptop fax

Whenever I turn on the pc for a while, the resolution suddenly changes, or it just makes a lot of noise

could that have something to do with my display exchange?

In principle, yes. Bad contact of a Flexband in heat.

In heat…

then I know why because my laptop has no active cooling and is very hot so I have to look that I get a cool pad for the laptop
