Hello guys! So I just finished building my friends new rig, as payment he gave me his PNY GTX 570 as payment. I just installed it and all seemed well till I started my first game (Far cry 3) and a soon as it was done loading the screen went black and audio looped and then it rebooted. I tried various other games to have the same thing happen. I tried upping the voltage to no avail. Even minecraft caused it to reboot. Im also sure its not the PSU as I can run two 8800 gts cards in sli just fine. Any Ideas?
