    Coprocessor - Devices not installed

    I'm new to Windows 8 and I'm having a hard time managing my way around. My windows automatically installed almost all of my drivers, but failed to recognize the coprocessor. When i open the properties it says:
    The drivers for this device are not installed. (Code 28)

    To find a driver for this device, click Update Driver.

    When i try to find the driver automatically,it fails, but i cant find them aswell.

    My motherboard is ASROCK 939a8x-m, therefore it has an nvidia chipset in it. I fail to find the neccessary drivers aswell and i don't know what else to do.

    Can someone please help me with this?

    You can always use the Hardware ID found in device manager to know the exact driver you need to find. This website will help you find it, based on that info:

    If there are any drivers for Vista/win7, try using those. Coprocessors (Math, floating point) are incorporated with CPU ever since 386/486 DX processors. Look for processor/MB drivers at Nvidia site.
