It sounds like your video-card is kicking the bucket. Remember that while some parts have a 10 year life-line, temp conditions determine a lot of variables in card's lifetime.

Try opening your case and taking out your video-card, use a compressed air can to blow out any dust that's in the heatsink. Do the same with your case. (Outside or in a wide open area or the dust will just re-circulate into your components)

Uninstall and reinstall drivers for it. Try changing the resolution a few times.

If this doesn't work, also run your system and see if the fan on the video-card is actually turning on. Check the cable from the card's fan to the thing it connects to, make sure it's fastened and secure.

If none of this stuff is a problem or solves the problem, I'm pretty sure your card is going out.
