I have a newly built PC: 2GB Kingston RAM, EVGA 8800 GTS (320 MB) VGA on Windows Vista. I was playing Medal of Honor Airborne with excellent performance until this error showed up. I played for like 6 hours before it started showing up. Now it shows up in the game and when i run Windows Media Player in full screen. Paid for Driver Cleaner .NET hoping to do a new installation of the nvida drivers (163.69) instead of the older (162.22). When I removed the old driver and before installing the new one, I was able to run a video in Windows Media Player in full screen without a problem. When there is an Nvidia Driver installed the problem returns. I also notice trails of red dots appearing when I drag any window over the desktop. Please help me solve this, does Driver Cleaner help here?
