I'm guessing this is the beginning of the end for my CPU,good thing I've just ordered the new haswell i5. Is there anything I can do to try and stop it from turning itself off? I've used cpu temp and while I can't see any obvious signs of over heating, I have done a time log of my CPU and this game is working it,hard.

So I strongly believe it is overheating, just can't get the temps while I play.
