No power to my new mainboard

[kony]

As I said, I did strip it down to the bare essentials, main board,
power supply, video board, monitor, and it still didn’t work, until I
cleared the CMOS, and then it did. But now I don’t know how to set
the CMOS, because every time it goes back to an unusable
configuration.

Yes, but this thread has been so round-about and
disorganized that I'm beginning to forget even what's been
discussed.

My impression is that you have either a user
misconfiguration of cables/cards/etc, a faulty motherboard,
or inadequate power supply. I'm not sure of this, but am
out of ideas. If you have some spare parts you could swap
in it might help. That's all I have to offer, if I had to
GUESS at which part was the problem that guess would be the
motherboard, that you should return it to seller if
possible.

I checked the voltage at the two main points where it
connects to the mainboard, and it was about 2-3 mV at
each.

Just so you can be sure you are measuring voltage correctly, measure
the voltage of a 1.5V battery.

I had a passing thought that maybe this was a measurement of
the video card output still, but I thought I'd covered that.
In case there is still that confusion I meant measurements
of the power supply voltages.

This system might be a good candidate for the local computer
shop, if nothing else they have some spare parts around.
