SYMPTOMS
When you change your Windows NT display driver, this message appears:

At least one service or driver failed during system startup. Use Event Viewer to examine the event log for details.

The event log says that this message is caused by the driver of your old display adapter or another display you have installed.



CAUSE
When you install a new display driver, the display applet disables the old driver if the Disable current driver check box is selected. One of the following causes may not allow a driver to identify the new graphics adapter.


 * You first installed the wrong display driver and then the correct one.
 * You changed your graphics adapter and booted with an entry from BOOT.INI which resets the display to /BASEVIDEO.
 * You changed your graphics adapter and booted normally. Your computer reverted to standard VGA when the previously used driver did not find the old graphics adapter.

The applet disables only the currently used driver. It does not disable any previous drivers that have been installed.



RESOLUTION
Disable the driver manually. Do this with the Deinstall button in the Display Applet or by changing the startup value for the driver you want to disable in the Devices Applet.

NOTE: The Deinstall button does not actually delete the driver files. It only disables the driver in the registry.
