I'm running one machine here on Win98. I know. I know. It's old. But it's necessary. The video card is NVIDIA RIVA TNT2 MODEL 64. The problem is that the video display, some time ago, started showing ghost shadow lines across the screen on either side of whatever is displaying on the screen. I thought perhaps the monitor was dying, so replaced it. Funny things the display still shows the same problem. As near as I can tell I have an update driver. (Got it from Gateway - the manufacturer of this machine). Am I looking at a video card that is dying?
