Hey everyone So a friend of mine just built a new PC. Every once in a while (5 minute to to 1 hour intervals) the PC will freeze. It doesn't blue screen or anything, just straight up freeze. The only way to unfreeze is force shut down and restart. The strange part is it doesn't seem to freeze during gaming. It will freeze while web browsing, or any other light task, but doesn't freeze in games. I took a trip to his house yesterday to see what was going on. When I got there he was playing a game of hearthstone. As soon as he hit the quit button, the PC froze. We then spent 2 hours trying to recreate another freeze. We finally managed to get another while playing a flash game. The PC then froze a few more times, but we still couldn't find anything that seemed to cause it. My friend though that his windows install might have messed up, so we did a fresh install. This didn't help. I don't know if anyone had had a problem like this, or might now how to fix it. I'm heading back over there today.
