When I leave my homemade PC idle for 20-60 minutes, it randomly freezes, and I have to force restart, stopping me from downloading any games. If I am using it for browsing or video games, it never freezes. I have tried every test their is, and i have narrowed it down to a problem with the CPU. Would anyone know a way to fix this, or if not do you think I should buy a new CPU? Thank you for helping
