Is it possible that powercolor x800xl can just die because of slightly lower than normal cooling (I had it manually set to 30%, also running at 420/520). Anyways computer didn't boot after it crashed, no display or anything im pretty sure its the card, because motherboard without it beeps and with it it doesnt do anything just locks up in blank screen. Has anyone experienced anything like this and is it possible to just "resurect" it? pls help
