Hi, I have the GA-MA78GM-S2H and it simply poweroffs when playing games - no bluescreen, nothing in the event log. The severity seems dependent on the game and lately trying to play Arkham Asylum has been murder. I've read around some sites and there's been plenty of people complaining about the inadequate Rev 1.0 heatsink on the northbridge. With Rev 1.1 (and later 2.0) it seems all gigabyte did was put on a larger heatsink on the northbridge.
I was thinking of RMA'ing the whole board but rather than having to ship the whole thing to them and waiting however long for it the be sent back is it possible for gigabyte to just send me a new replacement heatsink? Maybe the one found on the rev. 1.1 board?
(I've also checked all the other components and the temps coming off the heatsink are enough to boil water, i'm pretty sure that's the problem).
