TROUBLESHOOTING
Obtaining a Usable Video Resolution
The system operates in VGA mode when the video display driver is not running to accommodate all
monitor types. VGA mode is used during initial installation of the video display driver and when
experiencing video problems. If you select a resolution that causes the monitor to display incorrectly, try
the following proceedures to obtain a usable video resolution.
Using the Last Known Good option in Windows NT
Press CTRL+ALT+DEL but do not log on to the Windows NT operating system. Instead, shut down then
use the Last Known Good option to return to the last known good configuration recorded by Windows
NT.
1. Restart the system.
2. Press
the
SPACE BAR
at the following prompt: Press space bar NOW to invoke the Last
Known Good Menu .
NOTE: If this option fails to correct the video display problem, restart the system in VGA
mode, and reconfigure your display to 640 x 480 resolution, 60 Hz refresh rate.
Then restart Windows NT again in non-VGA mode.
Booting into Safe Mode
Press CTRL+ALT+DEL but do not log on to the Windows 2000 or Windows XP operating system.
Instead, shut down then boot into Safe Mode to choose another resolution or reinstall the video driver.
1. Restart the system.
2. At the boot screen, hit F8 to enter the advanced options menu.
3. Choose Safe Mode, then hit E
NTER
to return to the boot screen.
NOTE: If this option fails to correct the video display problem, restart the system in VGA
mode and reconfigure your display to 640 x 480 resolution, 60 Hz refresh rate.
Then restart Windows again in non-VGA mode.
