Today I replaced my old 7700 with a new NVidia 780. I attempted to turn on the computer and when I did everything lit up, then immediately shut off. I then took out the card and the cable, then tried a reboot, it still didn't work. My psu is 1000 watts and have enough power. While doing the installation, I wore an anti-static wrist band. What could have caused this?
