Question about ASUS P4P800-MX Motherboard
This may not solve your problem, but it does sound like your power supply may be the culprit. Find a paperclip. (Yes a paperclip. I'm not kidding.) pull the large 24 pin power connecter off of the motherboard (there will be a little plastic latch you need to press to get it off) and any other plugs coming from the power-supply should also be disconnected. Next streighten out the paper-clip and then bend it into a 'u' shape. With the power supply unplugged from everything but the cable going to the wall stick one end of the paperclip into the hole where the green wire connects and the other end into any hole where any one of the black wires connect on the 24 pin power adapter. If the power light turns on and you see the fan going the Power supply may yet be good. However, if the light doesn't come on and the fan in the power supply doesn't spin chances are your power supply is dead and you will need a new one. Be sure to remove it from the case and bring it to a local shop as some HP's use non-standard form factor Power Supply Units. The parts shop will be able to match up your Power Supply with something of the same form factor and similar or better wattage.
If it's not the power supply please post your results and we can diag from there.
