help :\

ok, I went to my graphics card webpage, which btw i have Radeon7200 VE. I have windowsXP. I downloaded the opengl drivers, and I am not sure where to extract them to. I extracted them, but, when I tried to switch my video mode in a game to opengl, the game says that video mode is not supported by my video card…?? Can anyone tell me where I extract them and any extra advice they have.
