I think it's overheating because it's incredibly hot when I touch it but I've opened the case and put a fan right next to it and still freezes and goes all pixaly. It also says that the driver has stopped working then recovered when I alt tabbed so, I tried different GPU drivers and updated to the latest version and that still didn't work. Help would be greatly appreciated
Here's a picture of what the screen looks like when it's pixalated
here are my specs ask me if you need more info:
