Self-rebuilt Gateway desktop Power Issues

Intel D915gux motherboard
June 23, 2010 at 17:03:15
Specs: Windows XP
I recently started a rebuild on an Gateway 554GE with a literally burned 2x2 CPU plug. (I found a screw lodged between the board and the case) I tossed the mobo , PSU, and the CPU and bought a used Intel D915GUX mobo, a tested working used Intel Celeron D 3.06GHz/256/533 CPU, and an off-brand new PSU.
The problem is that I re-assembled everything, but the system will not power on with the CPU 2x2 plugged in? All I get is the green light on the board and the blue power button light. If I leave it unplugged all lights and fans come on but the system will not boot without the CPU. I have removed the system from the case and have set it up outside the case to be sure it was not shorting out, but still get the same results. I also have tried a second known good PSU and another mobo known good, and another CPU 3.00Ghz Intel Celeron as well. I am using the integrated graphics on the mobo. I really am stumped on this. I have seen a couple of other post similar to this, but no answers. Any help would be appreciated.

The motherboard is most likely a dud.

Didn't you ask this already? You need to pull all the hardware out of the case & benchtest the primary components.

Thank you for the responses. I have tried another identical mobo that was pulled from working unit and get the same results. All of the components have been tested separately and test good. I removed all components out of the case and set it up on my workbench to determine if the unit was shorting out. Is it possible that since this board was originally in a Dell system, that I would need to have a Dell PSU? I have not heard of this on any other units, but I really am stumped.

Unlikely with a recent motherboard. Dell power supplies from before about 2003 (I think) used a proprietary power supply, but newer ones used standard ATX.

Ordered a new PSU today, I'll try another 650W and see what happens. Thanks for your replies.
