So for the past couple of months my computer will start to freeze after an hour of gaming. For a while I thought it had been my video card, which I replaced and am still getting the same problems. I figured it was an overheating issue, but when I researched what normal temperatures should be, they all seemed to be okay (I will post temps below). I have no viruses, my hard drive is not corrupted and does not have bad sectors. I don't play at the highest settings either. Please send me some suggestions.
Games I play: SC2, Mass Effect, HON, CS:S, and others.
