(You have to completely power down then power back up.)
Look at all the capacitors, specifically the larger ones.
If they are bulged (the tops should be absolutely flat), or at an angle on the board (probably due to blow out from the bottom) - you more than likely have bad caps.
From there, pull each one using some solder wick, and a 450 degree (celsius) soldering iron. As you pull each one, make notes of what came out of where, and it'* capacitance/voltage values, and most importantly, it'* polarity (if you mount one 'backwards', you'll probably get an impressive display of a capacitor imitating a firecracker).
Order new caps from badcaps (I got mine 2 days after ordering, I think I spent around $20 for a full set of about 10 to 12). Also don't go to radio shack for replacements - they most likely won't have the right value caps, and even if they do, they aren't rated for use in motherboards.
Solder back in, power up.
You have to be patient - the solder traces are tiny. Worst case is you ruin a board that didn't work anyway, but it'* best to practice on an old motherboard if you have one.
