I went out and bought a new power supply at CompUSA this morning. A new 500 watt power supply in place of the 460 I used to have. Plugged everything back in, the computer started up fine. Nothing was fried other than the power supply. Opened the old power supply just to have a look. Found 2 blown out capacitors rattling around inside it. I'm happy that this only cost me 100 dollars to fix.
