It turns out that the new mobo/cpu i dropped in was hogging the amps on my power supply rails, so the gfx card wasn't getting enough juice. I went from a 500w supply to 1000w supply, and problem was solved.

Hope this helps.

Wow I had not noticed his power supply. 500 is a bit weak these days when it comes to running a pc. That certainly could be it. When my mainboard and power supply went out I upgraded my power supply with them both to make sure I would not have that issue because when they went out I switched to a better board and ram as well.
