I've tried some new things and now I'm worse off then that I was. I decided to get rid of the overclocking so I went into the BIOS, changed the overclock settings back from manual to auto, saved and tried to load into windows. After the normal bootup stuff before it looks for an OS it just sat there with a blank screen. I rebooted again and nothing happened, the fans turned on but there was a blank screen, no POST beeps. So the next thing I tried was to remove the new video card. I did, remembering to move the SLI selector card back to single and to remove the EZ plug molex and I rebooted. Got a blank screen and the motherboard beeped one long and three short and played the message "System VGA Failure". I had previously forced SLI through the BIOS because it had not auto-detected it so I decided to wipe the CMOS. Did that, same result. Decided to pull my old card from the primary slot and put the new one in. Same result. Plugged the EZ molex back in, same result. I'm at a loss.
