Up until a few weeks ago, I've had very good performance in games. I got 60+ FPS on just about everything on max settings. Then, a few days ago my performance suddenly became shit. Practically overnight. Before I could get 300+ FPS in CS:GO, now it drops to 30, and doesn't go higher than 75. I also noticed that the temperature of my CPU rose dramatically, up to 100 C. I haven't done anything to cause this increase in temp, it's at stock clock speed, the cooling works fine, and there's no lack of thermal paste. Scanning for viruses comes up with nothing. I've also cleaned out the inside of my PC, but that hasn't done much. I've still got 400 GB free on my hard drive.
