I have a brand new OptiPlex 9010 All-in-one computer that was reloaded with Windows 7 Enterprise 32 bit. I downloaded all of the drivers from Dell Support and I still have one conflict in Device Manager. It says Simple PCI Communications Controller. The location says PCI bus 0, device 22, function 0. I can't find the driver to get rid of this anywhere. The PCI communications controller may be simple but this solution sure isn't! Any help would be greatly appreciated.
