Have you tried downloading the latest drivers, 197.45 from nVidia's website?
Your symptoms sound more like artifacts though...
I agree. color and lines is usually and artifact problem, not driver. Seeing as its an "older" card, try removing it and cleaning the heatsink. Remove as much dust as you can, and make sure when you plug it back in the fan is spinning.
