OK i was on VISTA playing some Age Of Conan and all of sudden my graphics start flippin out. Colors got distorted everything was just wrong so i restart hoping it would fix the problem but then it came back over and over. So one day i restarted the computer i see the Vista loading screen then bam the screen goes black. I can hear it turn on but nothing shows up on the screen. And i restart it again but i log into my XP and the problem is there too, my screen just turns blank after the loading screen. So I pop out the card and try my other 2 cards and there giving me the same problem.
