I had the same problem. I was using a none Windows screensaver. It turns out it was not compatible with Vista...yet!
Use one of the standard Vista screensavers and see what happens. Just an idea![]()
Hi. I'm running Vista Ultimate on a core2duo system with an EVGA 7900GT video card. Vista runs great but when I leave my pc running and come back later, I have garbage on the screen (either a white or green color with lines running through it). I first thought it was just a sleep mode problem and changed the power management settings to never sleep. After leaving the computer long enough for the screen saver to kick in and the screen to turn off, I checked it again and had the same problem.
Any ideas what could be causing this issue? Vista automatically downloaded updated drivers for my video card.
