Possible Solution
• Verify that the installation instructions were properly
followed.
• Check that the card is properly installed in your
system and connected to your monitor.
• If you have problems during start-up, restart your
computer in Safe Mode.
While starting Windows® 2000 and Windows® XP,
press and hold F8 until you see the Windows®
Advanced Options Menu. Use the arrow keys to select
Safe Mode, and press Enter.
• Check the system configuration utility of your
operating system for the interrupt assignments.
• Contact ATI's Customer Care or your local technical
support.
• Check that the card is seated properly in its expansion
slot.
• Ensure that the monitor cable is securely fastened to
the card.
• Make sure that the monitor and computer are plugged
in and receiving power.
• If necessary, disable any built-in graphics capabilities
on your mother board. For more information, consult
your computer's manual or manufacturer. (Note:
some manufacturers do not allow the built-in graphics
to be disabled or to become the secondary display.)
• Make sure that you selected the appropriate monitor
when you installed your enhanced driver.
• Check if your monitor supports the resolution,
horizontal (kHz) and vertical (Hz) refresh rates as
required by the graphics card.
• Check your current resolution, refresh rate, and color
depth settings in the Settings and Monitor tabs in
your Display Properties dialog.
Warning! Ensure that both video card and monitor
support resolution and refresh rates you select.
Incompatible resolution/refresh rate selection may result in
monitor damage. Refer to your monitor's documentation
for recommended resolutions and refresh rates.
