Holy crap!...so I just bought a new power supply from Best Buy...just to rule out the possibility that the power supply got fried and after I hooked it up, there literally was a spark that came off the cpu/heatsink fan! I unplugged it and then tried it again a little while later and the fan would turn on for a little while, stop, and then come on again....and it would keep doing this until i shut off the power supply switch.
