Resolution Problem After Updating Drivers

Since one version of the nVidia driver, at the end of the installation, and after rebooting; the resolution changes to 640x350. I first found this in RC, and even in the final version, it still happens. Once I change it back after reboot, it stays at that. But, I was curious if anyone else here has experienced that problem?

I have an 8800gts [I know, I should upgrade soon]

Can you manually change the resolution?

I can change it back to my native res, then it stays at that. It just seems strange it goes to 640x350, while before it would stay at 1024x768

Doesn't happen to me :I I'm using a GTX 260, but even when i was trying out windows 7 with my 8800GTS 320 that wasn't happening.
