    What exactly do you mean a "VGA compatibility problem" and in what way is it common (post link(s) to what you're referring to)? Explain the problem in more detail...

    Have you installed all of the device drivers for your PC after reinstalling Windows?

    Click Start>Run>devmgmt.msc>Ok. See any question marks on your devices in this window?

    You probably didn't install the proper video drivers. The PCI Simple Communications Controller drivers are more than likely drivers to a 56k modem you have installed in your PC.

    Please post your Dell Service Tag. How to find your Service Tag...

    Hmmmmm....

    Have you tried uninstalling the driver via device manager? The system should automatically detect the HW and reinstall the driver on startup :)

    dell has great web support page. Visit dell and enter your model number, they should carry all the drivers for your machine
