This trouble occurs when you upgrade from Win 7 which is fully-supported by Dell on these machines, to the unsupported Win 8 or Win 10.

Note: If the manufacturer only lists drivers for Windows XP and not for Windows Vista or Windows 7, that means the device is unsupported or incompatible with the unlisted operating.

Our Clackamas Oregon model RR club has two Dell Optiplex 755 laptops purchased used from a recycle store. The one that communicates with our layout NCE power module through the serial port has stopped communicating and Windows Vista device manager reports the PCI serial port driver is missing and also the PCI simple communications controller and PCI bus controller drivers. I have searched for hours on the Dell support download site for these drivers and cannot find any help. I even ran a Dell diagnostic package and it reported no problems. Any suggestions or how to find the proper drivers will be greatly appreciated. Danny Gatton Licks And Tricks Pdf Editor.
