It could still be your power supply.  Just because it turns on doesn't 
mean that it's supplying the correct, or even all the different voltages 
it needs to.

If you can put a spare power supply on it, or hook your current power 
supply to a proper tester, that would at least eliminate that from the 
possible problems.

The fact that the motherboard doesn't tell the power supply to turn on, 
but the power supply can be turned on does kinda point to the motherboard.

You should, but not always, be getting at least some beeps if the 
motherboard is good but RAM and/or CPU are a problem... Is your PC 
speaker hooked up so that you can hear them?
