So I finally got my D0 CPU in the mail and threw my new machine together. The LEDs for the three occupied dimm slots were illuminatedWent into BIOS and set voltage on RAM to 1.64v and everything ran smoothly. Installed windows and video cards with no hiccups. Set up my Crossfire and closed the case up. Moved the beast upstairs, plugged it in and got a message stating that overclocking failed. Resetting completely hung the system.

It now refuses to enter either the OS or BIOS. Only one of the dimm slots' LEDs are illuminated (A1), and pressing any buttons does nothing. It will actually only send out a signal to the monitor about half the time its turned on (powers up fine; fans spin, video cards blowing air), but nothing shows up on the screen.

Anytime I try to go into BIOS or the OS, it freezes. Everything fell apart when I powered off after finishing video card install/Crossfire Enable, so I'm inclined to think the problem is there. Opinions, advice?
