I am running Windows 7 Ultimate, very old machine. All is good with the exception of Cd Rom drive. It will accept and turn a disc for a moment, but Pc never loads info. I opened - Control Panel> All Control Panel Items> Troubleshooting. Clicked Troubleshooting Hardware & Devices. It detected a problem with the CDDVDRW device stating : A driver for this device has been disabled, an alternate driver maybe providing this function ( Code 32 ). So I view the Device properties and see Device Details, Update Device, Roll Back Device, Disable Device and Uninstall Devise. The Roll Back Devise will not 'Highlight' when scrolled over. Help finding solution would be fantastical. Can't make cd or download programs.....
