Mini GaGa

Hello everyone,
I have a big problem SO, please help me

I have bought new video card for my PC it is: ((NVIDIA GeForce 8600 GT 512 MB AGP)) Ok...
The video card cames with it CD Put the CD works only on XP
Today i have installed Windows 7 ultimate 32 bit so, after installation complete the windows automatically installed the video card as a standered VGA card with only 64MB VGA.
when I insert the CD comes with the video card it says it works only with windows XP
so, I downloaded another one from nvidia Official website for windows seven and i tried to install he says ((The program doesn't find any Devices)).
