Yes, i just did that g-paq
1) took MOBO out, only connections
POWER SW - which is the power switch to the case
2x12 pin FROM THE POWER SUPPLY
775 Socket E2160 CPU
Standard heat sink - connected to the MOBO cpu fan slot
Thats it, turned the power on the CPU fan moves a little wait 1 seconds the CPU fan goes, wait 1 more second the computer Shuts Off, is this normal? This is w/o ram or graphics cards or anything else attached, its not in the case.
