I have an hp ex475 that will not power up and need help in figuring out the problem. I posted the problem statement below on the HP MSS forum but then thought I should have really posted it here. If you can help I would appreciate it!

I have an Ex475 that will not power up and have gone as far as I can on my own in trying to figure out what is wrong. If anyone could offer some advice I would appreciate it a great deal.
Two weeks ago we had a power outage so my MSS was powered off. It was plugged into a surge protector though. Now it will not turn on when the button on the back is pressed. I figured it was the power supply so I disassembled the server and tested the power supply. I expected it to be dead but it appears it is not. When I put a jumper between pins 1 and 2 on the Molex connector the fan starts. Then I tested the voltages on all the other pins and they match what they are supposed to. So I put the power supply and all the other components back into the case and tried it again. Still, the server does not power up. Interesting thing, the USB outlets on the server do have power.
So, am I correct in thinking that there is nothing wrong with the power supply? And the big question, what else could it be? Am I just dead in the water? Any options at all? I have so much data on the two hard drives!
Thank you!
