No PCI Communications Driver for Optiplex 755

    Question

  • After installation, there are those pesky little yellow triangles in Device Manager, next to the PCI Communications Driver, as well as the serial port driver and one other.  Doing a web search, it seems like people had this same problem with the Windows7 beta as well.  When I tried to install Windows7 64 bit drivers from the Dell web site, they errored saying I had the wrong operating system.

    The wireless system seems to be missing or disabled, yet device manager reports the device is there, with driver installed and working properly.  My guess is that since it's a PCI wireless card, themissing PCI Communications driver may be the problem with that.

    Too bad, I was thinking the Metro interface might be good for my preschoolers.

  • Windows 8 is still under test and deployment and these type of compatibility issues are as expected. At this case, I also suggest to report it to dell or post it to Dell forum and you have to wait untill driver develop for this version. I also suggest that run troubleshoot hardware from Action Center in control panel and if it asked to report this send all reports.

  • A PCI Simple Communications Controller is a dial-up modem (unless Windows has misidentified the device).

    If you can identify the chipsets for the devices their generic Windows 7 drivers will probably install. The Dell driver installers will check more rigorously than the generic driver installers.

  • What was bothering me most was that none of the tiles on the Start screen would run.  That kind of kills the developer preview.  Also I couldn't get the wireless to work.

    It turns out that the driver for the integrated graphics didn't want to load because this operating system wasn't on the driver's little list.  Rather than fight that driver issue, I bought a graphics card, and once its driver loaded, the machine appeared to meet the graphics requirement for Developer Preview and the tiles started to work.
