Motherboard voltage sensors

[mdroc1]

Dear all,

I have an ASUS A7N-266VM motherboard. Recently, I put in a new CPU (Athlon) and a new power supply (400W).
When I turn it on, it prompts me to go into the bios and check out the power management settings.
They are as follows:
+3.3V = 4.08V
+5V = 4.92V
+12V = 12.22V
-12V = -15.94V
-5V = -6.12V

Clearly I have a problem here.
Question one: what are all these voltage measurements - ie.. what are they telling me???
Question two: what is causing the problem?
Question three: how do I fix it?

Any help would be much appreciated.

Can you try a different power supply? Is it a name brand unit? I think the easiest thing to do will be to replace the power supply.

I just replaces the power supply.
I put in a 400W and got rid of the old one.

Anything else I could try?
And by the way, what do these voltage measurements represent?
