Troubleshooting Guidelines
Gathering Information
Troubleshooting starts with diagnosis and progresses to solution. Before
diagnosis can begin, you’ll need to collect some information. This is
especially important if you don’t already know the contents of the
computer.
o See if the monitor cable is securely attached to the graphics board.
Loose cables are the most common cause of board problems. If it is
loose, secure it now and see if the graphics card functions with the
computer.
o See if the graphics card is seated correctly in the AGP slot on the
motherboard. If it is not seated correctly, remove the card with the
computer power off and reseat it, making sure the entire connector is
flush inside of the slot.
o Find out what other cards are in the computer. Cards can conflict
with one another, and resolution of these conflicts varies depending
on what boards are present.
o Find out what versions of the G740A/G740B Graphics Accelerator
display drivers and related software such as DirectX are installed in
the computer. You may need to update to the latest drivers by
downloading them from the World Wide Web. Contact your Field
Sales Representative if you do not know how to get the latest
G740A/G740B Graphics Accelerator display drivers.
o Gather some history. Did the graphics card ever work in this
computer? If so, was anything added to the computer just before the
card stopped working? Was the graphics card moved from a different
computer where it was working fine? Is the graphics card new? The
answers to these questions will speed up diagnosis dramatically.

The Solution Table
For each solution code associated with your graphics card’s symptom,
look up the code in the Solution Table for the recommended action. You
may need to try several possibilities to fix the problem.
Solution
Code
1 Verify that the monitor cable is attached to the connector on
the back of the graphics card.
2 The G740A/G740B Graphics Accelerator display driver may
be trying to use settings your monitor doesn’t support. This
could happen if a monitor was never selected in the software
and you changed your display resolution to one your monitor
doesn’t support, or if you changed the monitor connected to
your computer without changing it in the software.
3 Some computers may not properly detect the addition or
change of an internal PCI card. On start-up, a computer may
beep differently from normal to indicate this error. Reset your
computer’s CMOS. This is usually done through a switch or
jumper on the motherboard of your computer. Check your
system manual or contact your computer vendor for
instructions on how to do this.

detected incorrectly. If another graphics card is plugged into
an expansion slot, remove it. If a graphics chip is built-in to
your computer motherboard, your system may not have
automatically disabled it when you installed your
G740A/G740B Graphics Accelerator card. Check your
system manual for instructions on how to manually disable the
built-in graphics chip.
5 There could be a conflict between the application and the
G740A/G740B Graphics Accelerator card. Make sure that you
have installed the latest available display drivers. Try disabling
Hardware Acceleration in the Advanced Graphics Settings of
the System application in the Windows Control Panel if the
problem is specific to this application.
