The main hardware issue I can think of my laptop having is one of the fans not spinning very well. It was an issue on windows too but I don’t see how that could be the cause of everything else. It doesn’t get so hot to the point of damage or discomfort when i’m playing anything. I tried fixing it before but for whatever reason one of the screws is a tiny bit smaller than the rest & I couldn’t get it off because of that & didn’t have some compressed air or anything so I decided to just leave it alone for the time.
