Windows 7: Login screen and "User Account Control" Dialog Corrupted

Login screen and "User Account Control" Dialog Corrupted

After a clean install of Windows 7 and installing both current NVidia (GeForce 7800GS AGP) drivers and monitor driver (ACER W223X) I was able to get Windows & to run in my monitor's native resolution (1680x1050) but no matter what resolution I run in I get some weird effects. When in the 'Login Screen' I get short black lines scattered about the screen and the controls are all corrupted. Once logged in and on the desktop the graphics are all good with no issues at all. That is until I try to do something that requires Windows to toss me the "User Account Control" dialog.
The dialog is corrupted (see attached) except for the "No" button which is obviously the default and therefore has focus. As I move the mouse over the "Yes" button it gains focus and it becomes clear and visible. The background, although dimmed, displays just fine. If I drag the dialog around the screen, the "No" button leaves copies of itself like mousetracks. When I click yes or no and the dialog closes, the display goes back to normal. This occured both during Windows installation and after it was completed. I just assumed that once the updated drivers were installed it would go away. NOT!
I am guessing Windows is changing the display resolution when dimming the screen or in the login screen. ?? I have exhausted myself trying Vista drivers, XP drivers, Windows default drivers... I have tried about 10 different versions and still no change. Suggestions. Is this an AGP/PCI issue with W7?

Video card memory gone bad maybe? Overlap conflict between video and system memory. Possibly need a updated video driver?

Replaced my NVidia with a 6600 AMD PCIe video card and poof, problem gone. I am assuming that this was an issue with the AGP and windows 7.
