View Full Version : Garbled screen when changing resolutions

07-03-08, 03:17 AM
I'm running Vista x64 SP1, 7900GT and the 175.19 driver. Whenever a game needs to change resolution or if i manually change it then the screen becomes garbled. I need to restart the PC to fix the problem. Anyone have any ideas? Everything works fine in XP so I don't think this is a video card issue...

Did you try turning your monitor off, waiting a few seconds, then turning it back on again?

175.19s have had a lot of issues. I'd roll back to the 175.16s or load the 177.39s with a modded .inf.

Thanks for the replies. I eventually found out it's a known issue with overclocked 7900gt cards and Vista. Once I underclocked the card slightly with nTune then the issue was fixed...
