Data loss is not related to the motherboard. If you're convinced that you
need a motherboard, then now is a great time to consider an upgrade. Any
data that is lost or retained is in the HDD, so you can makek changes to the
motherboard and not affect the data loss/retention part of the problem.

Your test of the PSU is inconclusive at best. If you have a bad PSU that is
not able to feed ALL OF THE VOLTAGES, but it does feed SOME of them, then
you might have fans that can come on but not have other critical things take
place. A valid test is to name your machine A, and get another machine named
B. If your mother board fails in both A and B, then your motherboard is at
fault. If the motherboard from B works until you put it into A, and your
motherboard works in B but not A, then the Power Supply in A is highly

Nevermind, you swapped the PSU from B to A, and got no improvement in the
symptom set. This should be a good test, assuming B was working when you
took the power supply out of it, and worked again when you put it back. If
you put the supply from A into B, and B works, then this further supports
the integrity of the power supply, and points to the motherboard as the
fault source.

You also have one more item, the Boot Sector of the HDD. (There was
discussion of the RAM, and I don't recall what conclusion you drew from the
tests described there.)

You would isolate this by taking the HDD from B and installing it into A to
see if A will come up properly.

Update: I've got the keyboard registering now. But not much else
changing. Ethernet is still not detected. Awaiting the new
motherboard to come in...
