Hi. I'm running 9800GTX+ in SLi on XP SP3 and recently, suddenly, TF2 started getting horizontal bands going up and down the screen when I load it up. I can't screen shot it for some reason (screenshots show everythign fine). This implies a hardware problem to me, like my monitor, but this issue isn't consistent on any other program, so I'm really confused here.
The horizontal bands /stripes are translucent. Some bands darken the menu others lighten the menu. When I change the resolution, sometimes they go away. But if I tab in and out, the bands might come back.
Anyone have any ideas?
