Re: How to determine video-driver loading in XP ?

To verify exactly which video drivers you expect your Windows operating system to load, follow these steps:

Start Registry Editor (Regedit.exe).

Locate the following key in the registry:
HKEY_LOCAL_MACHINE\hardware\DeviceMap\Video

The Device\Video0 value points to a registry key that has the location of the video driver that Windows is configured to load.

For example, the value may be:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\videodriver\Device0

Locate the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\videodriver\Device0

To see what the value setting is, double-click the InstalledDisplayDrivers value.
The setting shows the driver that was loaded.

Re: How to determine video-driver loading in XP ?

If the setting shows another registry location, a third-party driver may be being loaded when Windows starts. If, for example, Symantec pcAnywhere is installed, Device0 does not have the name of a file. Instead Device0 has another registry location, and that location gives the video driver name. For example:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\AW_HOST\Video0.

Verify the following:
  • Verify that the driver file or files that are displayed in the registry key are present in the WinNT\System32 folder, where WinNT is the name of the folder that Windows is installed to. The relevant file or files have a .dll extension.
  • Verify that the file or files are also present in the WinNT\System32\Drivers folder. The file or files have a .sys extension.

Re: How to determine video-driver loading in XP ?

If the links and values are not correct, or if the files that the registry key points to are not present, correct the links and values so that the system starts properly.

If the links and values are correct, and the files are present, there may be a video driver conflict. Verify that you have the latest drivers for the video adapter.
