Okay I just found the problem I believe. Now I just need help figuring it out. Please!
Heres a picture.
So as you can see, my GPU Usage randomly spikes up to 100%, which would cause it to freeze. Everything else seems normal. The GPU usage a bit before that I was trying a game, which I was able to following play through a match in. (Starcraft 2!) I then tabbed out in amazement that it wasnt freezing, tabbed back in annnnd it froze. After I got it minimized, thats what I saw. What could cause this?
