I installed Windows 7 Home Edition and I get a warning icon for my Co-Processor under Device Manager. It says: "The drivers for this device are not installed. (Code 28) To find a driver for this device, click Update Driver." I click Update Driver and click Search Automatically for updated driver software and it says Windows was unable to install your coprocessor. So I go to Nvidia's site and search for Nforce drivers for 64-bit Windows 7 and it says drivers not found. Help me please.
