SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows Server 2008 or Windows Vista Service Pack 1 (SP1).
  • This computer supports hot-plugging of Peripheral Component Interconnect (PCI) Express graphics cards.
  • While the computer is asleep (S3) or in hibernation (S4), you hot-unplug a PCI Express graphics card.
  • You resume the computer from sleep or from hibernation.
In this scenario, when you open the Display settings item in Control Panel, you receive the following error message:
The currently selected graphics display driver can not be used. It was written for a previous version of Windows, and is no longer compatible with this version of Windows.
The system has been started using the default VGA driver.
On the Monitor tab, the unplugged graphics card is still listed. Additionally, if you reinsert the graphics card, the old item for the previously unplugged graphics card remains, and a new item for the same graphics card is added to the list of available graphics cards.

Note This problem does not occur if you unplug the graphics card by using the Safely Remove Device icon in the notification area.
