Received my RMA replacement for my previous defective motherboard (memory slots didn't work right, CPU socket was fine), which at least ran, and now in this build, the motherboard wont boot.
The first time I push the power button (after turning the PSU on), the lights flash for a half second and the fans barely start to spin, but then it goes dead. Subsequent presses of the power button do nothing.
I know it is not the power supply since it worked with my previous motherboard just fine, and also worked with the paper clip test (paper clip to green and black wire powers up the PSU fan). Removing the ATX 2x4 connector cause the motherboard to power on for a half second and then turn off repeatedly until I turned the PSU off. I also tried to reconnect the ATX plugs multiple times to no avail.
Also, have tried reseating the CPU, and have replaced the CMOS battery and cleared the CMOS.
I am running the computer outside the case, with the bare minimum set up needed to boot, so there is no possibility of a short.
Any ideas on why I can't power up? Would hate to have to RMA this board again and wait again!
Motheboard:
GIGABYTE GA-P55A-UD3 (Rev 2.0)
PSU:
OCZ ModXStream Pro OCZ700MXSP 700W
Thanks for the help!
