SYMPTOMS
After you upgrade your Microsoft Windows NT-based computer using a Matrox video adapter to Windows 2000, the Matrox QuickDesk and PowerDesk utilities no longer function properly.



CAUSE
This issue occurs because the Matrox video adapter tools for Windows NT 4.0 are incompatible with Windows 2000.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, contact Matrox to inquire about the availability of a fix for this issue at (514) 685-0270, or visit their Web site:

To work around this issue, disable the Matrox video adapter utilities:  Use Registry Editor to locate the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

Delete the following values:

MGA QuickDesk = "C:\Program Files\MGA NT

PowerDesk\QDesk\MGAQDESK.EXE"

MGA Hook = "C:\WINNT\System32\MGAHOOK.EXE"

Quit Registry Editor. Click Start, point to Settings, click Control Panel, and then double-click Services. Double-click the MGACTRL service. Under Startup Type, click Disabled, click OK, and then click Close. Restart the computer.</ol>
