sounds like the PS is bad by what you're describing. I say order one, worst case you'll have a spare.

mgb:

I would pretty safely bet the power supply is just blown. Its very typical.
I would just order a new power supply.

The one test you may want to do first is to remove the +5 and +12 volt lines off the ps and then test the power supply just to verify its not the board bogging down the voltage but I'm pretty sure you'll still find no voltage.

When you do change out the ps, its important to have it properly adjusted.
Without the board connected, quickly turn it on and maje sure you have 5-5.2 volts at the +5 volt output.
Then plugin the board and metter for voltage at the board this time (not at the ps)
You'll probably see about 4.8v or so.
Adjust the ps knob until you have about 5.1 v at the board.

Good luck
