Spec is in sig... just wondering as i've ironed out all my problems bar this one. So what causes a warm boot to fail? Cold boots are fine, it's just restarting that's the problem. It's like the computer switches off but doesn't have enough power to restart? It can't be a PSU compatibility issue as i have a Seasonic 600W which the A8N32 mobo has been advertised with, pfft. I've seen various people with problems with this board, but i can only get little information as to why it is doing it.
