Troubleshooting
This section describes how to solve problems which may occur with
your HP Matrox G450 Graphics Card.
If the computer
fails to start or if
the screen is
blank and there
are no error
messages
The computer
starts normally
but the screen is
blank or the
contents are
corrupted.
Solution
Explanation
Check that the computer and monitor are
turned on. (The power light should be
illuminated.)
These are useful routine checks,
especially if you have just moved the
computer or the monitor.
Check the monitor’s contrast and
brightness settings.
Make sure the power outlet is working.
Check that the graphics card is correctly
installed.
Solution
Explanation
Check that your monitor supports the
graphics card resolution and refresh rate.
If the monitor does not support the
selected resolution, boot in Safe mode
(Windows 95, Windows 98, Windows
2000) or VGA mode (Windows NT 4.0).
This problem may occur if you have
just changed your monitor.
The graphics card driver may be
corrupted or not properly installed.
Reboot in Safe mode (Windows 95,
Windows 98, Windows 2000) or VGA
mode (Windows NT 4.0).
If the driver files are corrupted, the
computer may boot but may be
unable to switch to high-resolution
mode.
Remove the graphics card and then
reinstall it. Ensure that the board is
properly inserted in the AGP slot.
The graphics card may not be seated
correctly. This causes the screen to
go blank at this point.
