I'm hoping that someone can help me with overheating problems I've been having. My computer specs are below. What's happening is I'm seeing graphics corruption in games, like flashing textures and strange colors, and also random lockups or crashes. This usually happens when the game has been on for a while which made me think it's a heat issue. I replaced two fans in my PC case that the bearings had gone bad on, but this hasn't helped. I'm wondering what is actually overheating, and what exactly I can do about it. I've been running CPUID to monitor temperatures and these are the temps I get while playing games: CPU Temp 100C (211F), GPU temp 88C (190F). Any help would be much appreciated.
