I have a brand new 600W psu, so that isn't the issue. I have updated my bio's, and everything runs smoothly with my old 550ti. However, when I insert the 960, it freezes at the boot screen, and the card completely powers down, the fans do not turn. The card gives a white light next to the six pin connector to show its installed correctly and is getting enough power. The bios only gives one beep on boot up. I'm guessing this card is DOA since I have tasked all possible causes and sent for another card. What do you guys think?
