Sorry for the late reply, I never saw another post...
I think it is the HD, personally. When I would start up games, there would be a squeeling noise coming from my tower.
How do I reset Video card and memory? EDIT: NVM, reseat... My bad... I'll do that with my ram, I already did with my video card.
It started freezing so that everything was stuck except for my mouse. But after two reformats it will freeze totally where I have to restart my PC. It only happens when I'm playing games or one time when I was loading music from a CD onto iTunes, talking on AIM, and browsing the internet.
After it froze I adjusted card placements so that the video card got as much cool air as possible. I put the ethernet card next to it because it was shortest hopefully reducing it to heatup.
I was told to find a better temperature program, where can I find one of those?
Thanks
