So, I just did a clean reformat with Windows XP media center edition yesterday and I'm having a really weird problem. Two programs, ATITools and OCCT (a CPU stability tester) make my computer make weird noises when they are running. I'm not talking through my headphones, but the computer itself. I can't really describe the noises, they're sort of a vibration, and both are different. I haven't had this problem before and I'm not having it with any other programs, so WTF?
