How do i unistall GFX card drivers?

i've just bought a 8800gts, and before i can install its drivers the manuel said unistall the drivers of my previous card (7300se), so can anyone tell me how to do this?

In safe mode, go to device manager, and in the video card properties sheet, go to uninstall.

Then you can shut down the PC and install the new card.

Thanks allot, and i can get to safe mode through bios setup page can't I?
