Then I'd check to make sure that the Video card is fully seated in its slot. Next I'd look at the heat situation in your case; it is well ventilated or is it in a place such as a cubby where there's no where for the vented heat to go? Try taking the side off of the tower and see if that stops the problem. If it's still continuing Id suggest finding a new video card.
My tower sits on top of my desk, right next to my monitor. There is nothing behind it and a good foot and a half between it and the wall behind.
I did remove the cover and blow the accumulated dust off earlier. As for the cable, I've disconnected/reconnected it so many times trying to figure out the problem that I'm 100% sure it's connected correctly.
Seems like the majority so far are suggesting it's the video card. I can tell you that the one I have is stock, an nVIDIA GeForce 6100. What would the average price be to replace it with something of the same or better quality?
