Something like this was happening to me when I downloaded new drivers for my 8800GT. So here is my experience.
This was from Age of Conan though. I decided to download the most recent driver for my card and OS. Well, after that was done, when I loaded the game up my screen would be black, The letters, Hotbars and maps showed up but the environment was all pitch black.
So, I fucked with the video settings in the game and found out that only High Performance actually allowed me to see what I was doing, killing or who was killing me.
Shortly after I started getting the Blue Screen causing me to flip the power. After awhile I said fuck it, I went into Control Panel, Programs and Features (Vista) and removed the video drivers and went back to the ones on the CD that came with the card. After that, my game play was fine again and no more Blue Screen.
After telling this to a tech friend of mine he told me I should check out
omegadrivers.com. They support ATI and Nvidia.
SOrry for the long post, figured I would share is all.
