I have been gaming a while on this PC and have found that it just restarts with some games. The restarts are not consistent in any form really. The most recent ones have occured with dawn of war II: chaos rising, I played the game for 4 hours the first night and nothing happened. The next day I got to this particular stage and restarts every time. I have also had restarts occur with left 4 dead 2 (after over an hour of play) and once with battlefield bad company 2 (after a very long time of play).
I suspect something is overheating (or thinks it is) but do not know how to test for it. It does not occur with all game, only seem. It seems to be random what games those are. My computer also has alot of fans so I find it hard to believe it is actually overheating (they all work, I checked).
My setup is:
Sapphire Radeon HD 4850 x2 crossfired
Gigabyte GA-EX58-UD5 mobo
Corsair Dominator 3 x 2GB DDR3 1600 memory
core i7 2.666ghz
850 w corsair psu
any ideas, or tests I could do would be great. I am clueless about what to do.
I also find that I get this error when I start back up (i think, im not sure of when it actually occurs). It doesnt appear there is any log of an error when I crash. Though I saw an error message up on my desktop for a brief second before it crashed.
