Using one of the drivers you have already downloaded for the geForce. (Remember where you extracted them to)

Right click on "My Computer", "Properties","Hardware", "Device Manager"

Click on the VGA adapter that is not installed. Click the update driver button and tell the wizard you will specify the location of the driver. Then next click "don't search. I will choose the driver to install". Click the "Display adapter" and "next". On the next screen click "have disk". Go to the folder where you extracted the drivers to and then you will see that you can click "Geforce 6100/6150 (whichever one you have)
