Advanced troubleshooting

These methods are intended for advanced computer users. If you are not comfortable with advanced troubleshooting, you might want to ask someone for help or contact support. For information about how to contact support, visit the following Microsoft Web site:

Method 1: Disable or update device drivers

1.	View the Microsoft Hardware Compatibility List (HCL) to determine whether the PCI devices in the computer are compatible with Windows XP. For information about the hardware compatibility list, visit the following Microsoft Web site: http://www.microsoft.com/whdc/hcl/default.mspx (http://www.microsoft.com/whdc/hcl/default.mspx)
2.	Update the video adapter drivers to the latest versions.
3.	If a driver is listed by name in the Stop error message, disable or remove that driver.
4.	Disable or remove any drivers or services that you recently added.

Note If the error occurs during the startup sequence, and the system partition is using the NTFS file system, you may be able to use safe mode to rename or to delete the faulty driver. If the driver is used as part of the system startup process in safe mode, you must start the computer by using the Recovery Console to use the file. For more information about video adapter drivers in safe mode, click the following article number to view the article in the Microsoft Knowledge Base: Note If the problem is associated with the Win32k.sys file, the problem may be caused by a third-party remote control program. To remove the service, use the Recovery Console to start the computer, and then delete the specified system service file.

Method 2: Adjust the Hardware Acceleration

1.	Click Start, click Control Panel, and then double-click Display.
2.	On the Settings tab, click Advanced, and then click the Troubleshoot tab.
3.	Move the Hardware Acceleration slider to None, and then click to clear the Enable write combining check box.
4.	Click OK, and then click OK.

Note This procedure prevents the graphics adapter from programming the hardware incorrectly, but you may lose some display functionality and performance. Although you can increase the hardware acceleration settings higher than None to regain functionality and performance, these settings increase the possibility that the issue will occur again. For maximum stability, leave hardware acceleration off.

The Stop error message may also occur in video adapter drivers that do not represent a physical device. For example, this Stop error message may occur in the virtual video adapter driver that is used by Symantec PCAnywhere. If PCAnywhere is installed on a computer where this error message occurs, visit the Symantec Web site to determine whether there are any available fixes for your version of PCAnywhere.
