I have been trying to update my graphics card to be able to play Battlefield 3 since it came out! I had the original drivers 263.08 and am trying to get any above that. I have tried 285.62 and 285.79 but they remove the switchable graphics option and I cannot open the Nvidia Control Panel. When I try to revert the driver back to 263.08, the install fails.

Right now I am without a graphics card because there are no drivers. What should I do?
