I updated to latest nvidia video drivers because of something, but now when I load quake3 it's stuck in 16bit. Counterstrike also opens in a window, I assume this is because it can't run in 32 but I'm not sure.

Desktop is running fine at 32bit.

This happened last time I updated my drivers for some reason, but I avoided it by just using the old drivers I was using because they were still in a folder on my comp.

I don't want to result to trial and error until I get some working ones because it's happened to more than one set of drivers, so any ideas please help thanks!
