Hello, Im new to this forum so hello everyone. I've got a little problem. I bought a ASUS HD4850(but with some shitty fan actualy, not the glaciator) and Chieftec 450W. My problem is: When I was playing Batman Arkham Asylum, my screen went black, comp lagged and i reseted the computer. For my bad, screen even at boot is black, card is normally starting, fan start, but there's no screen on monitor. BTW. Temperature of this card was about 70*C(!) at idle and 110*C(!) at playing for like 2-3 minutes. (then it restarted). Any possible solutions of this? Sorry for bad english.
