Hello,
I recently changed my motherboard, memory and CPU. It booted fine once ran for approx 6 hours with me working on it. Then I turned it off. Now when I power on, the fans come on the hard drive lights come on and the power lights come on but it does not boot or beep. No bios, nothing come on the monitor at all.

MB:ASUS P5Q-EM DO
CPU: INTEL E6800 (3.33GHz)
MEM: G.SKILL PC6400 DDR2 2GB X 4
VGA: GFORCE 9500 GT
PS: COOLMAX v600 (600W)

I just changed ps FROM AN ANTEC TPII-500 that was doing the same thing. No change with the new (COOLMAX) PS. no overclocking just standard installation. Dual boot from two HD's one XP and one WIN 7. WIN 7 is OEM and does not boot but I know the cause of that (New MB + registration)and unplugged it
