Total System Crash

Hey after playing the game for more than 20-30 mins my system does a total shutdown. I updated drivers and tried lowering the graphical settings to save on memory but the crash still occurs.

I have my crash log and dxdiag but the forum doesn't seem to support .rar or .7z file extensions, not sure what you want to do about that...

Same thing happens to me - same time period. My machine -never- crashes normally.

It feels like a thermal shutdown
