I don't have audio at work, so if I missed some details, I apologize.
Well, the motherboard knows it has reference/constant voltage, because the led is lit. I really liked when they added those to most board designs.
Since your power supply fan isn't spinning, I'd be inclinded to assume it's bad. Make sure the voltage on the back of the PS is set correctly (if it has the option) and that the external main switch is on (again, if the PS has one...cheap ones don't anymore). I assume that it is, since the motherboard again has reference voltage.
Press the power button on the case. If you're unsure of it making a click, you can probably remove it from the case and work it by hand. If pressing the button has no effect, such as starting the system or spinning up the PS fan, I'd assume the wiring from the switch to the MB is probably bad or wrong and start there.
After that, I'd swap in a known good ps and see what happens.

I've had that happen when a component plugged into the motherboard didn't jive well with the rest of the system - believe it, or not...
Try removing the video card first then try the power - then move on to the RAM and whatever else is plugged-in...
I had one system where I stripped everything down the bare motherboard before I could get the PS to power-up - then I started plugging things back in one-by-one before I found the culprit that was killing the PS - turned out, it was the sound card I had plugged-in...
