Supermicro Board Issue

[facecard]

I have a old PC with a Supermicro P6dgu board. Back in the day it was used as a Netware 4.11 server. It does get power and the computer does turn on. Occasionally, I do get video but it is very inconsistent. With everything connected I can't turn on the computer and video appears on the monitor. I have the computer stripped down to the bare minimum.

I have tried the following steps.

-Plug in a PS/2 mouse and keyboard and swapping ports
-Plug in USB mouse and keyboard and swapping ports
-Swapped AGP cards
-Cleared the CMOS

Sometimes the mouse and KB is recognized together or separately and other times not. I swap things...move things....remove something..... I can't narrow down the problem or have some consistency. I don't know if it is the power supply, MB itself, ports, etc... that is causing the problem.

I do understand it is old and outdated. It has been sitting around for 15+ years and not used. I thought I would play around with it.

Those problems are not uncommon on really old mobos.

Are there any bad swollen caps on the board?
That's one of the most common problems on old boards, the caps don't last but more than a few years sometimes.

You could try another PSU if you have one, but still wouldn't count on it running reliably.

The top of the CAPS look fine. No swelling either. No burnt spots or anything related. I did try another PS and continue with the same results. I understand the board is old and very picky.
