I've just gotten a new Q6600 installed into my 790i Ultra. After I installed the processor I get a long beep, blank screen, and the LCD reads 7F. I reset the cmos before installing the processor (and about 4 other times while troubleshooting). I've removed everything except the processor and ram. Also tried the old processor and get the same error. Prior to installing the quad the system had been up and running without issue. Q6600 and E8400 EVGA 790i Ultra 2 x 1g OCZ DDR3 1800 2 x 8800 gtx Auzentech X-Fi Prelude Any help will be appreciated.
