Mother Board issue most likely, wondering

[Adrenaline]

I have a Stacker 830. I had the motherboard tray replaced courtesy of CM due to my video cards not seating well (excellent customer service). Over three years later I am having an odd problem, the computer will shut itself off in windows and randomly try to reboot itself.

I have the problem narrowed down to one of three things:

CPU
Mother Board
Mother Board Tray

I have heard of problems with trays from 830s shorting out boards so what does this problem show as to the user?

This is only to help narrow down my problem, which I am convinced is the mother board but am just checking to be sure before I order one.

EVERYTHING is unplugged but the mother board with CPU in it and the system won't stay on for longer than 3 seconds. I orderred a new power supply and already installed it.

Any other suggestions would be most appreciated.

Mother board is an ASUS P5N32 SLI Deluxe that is three and a half years old. I would need one to replace it if this is the issue, so suggestions would be welcome. My CPU is a Pentium D 950. I plan on upgrading next year and not right now.

Try taking the mobo out of the case and benchtop testing it with just cpu and ram. Also use your old PSU to see if that was the culprit. If it will boot up and stay on on the benchtop then I'd say the mobo was most likely shorting in the case somewhere.

For some reason this is about the only thing I did not think of doing. I did this and it still tried to restart itself once but ran fine for an extended period of time.

So, I ordered a new mother board tray from CM. Thanks.

I am going to order a new board with and updated layout to hook up all of my hard drives as this board with my 7950 GX2s cover two of my SATA slots. Old cards I know, but they work for now. Just one more year and Im buying a whole new pc and monitor.
