I just got an Xtasy 5864 Geforce 2 Ti card and I randomly get a bunch of faint horizontal lines going up and down the screen (interlacing?). I tried the drivers from the cd and the newest from nvidia's site. Reinstalled my mobo's agp driver. Heat is not the problem, the fan on the card is working as are all other system fans. I'm running an Asus A7A266 w/1.4g athlon. Any suggestions before I exchange the card?
