Expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer.
- Turn off your computer and unplug power supply.
- Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.
- Place components on a grounded antistatic pad or on the bag that came with the components whenever the components are separated from the system.
The card contains sensitive electric components, which can be easily damaged by static electricity, so the card should be left in its original packing until it is installed.
Unpacking and installation should be done on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat.
Inspect the card carton for obvious damage. Shipping and handling may cause damage to your card. Be sure there are no shipping and handling damages on the card before proceeding.

DO NOT APPLY POWER TO YOUR SYSTEM IF IT HAS BEEN DAMAGED ON THE CARD.

In order to ensure your graphics card working correctly, please use official Gigabyte BIOS only. Use none official Gigabyte BIOS might cause problem on the graphics card.

3.3. BIOS Flash Utility
BIOS update procedure:
Note: Please download the newest BIOS from our website (www.gigabyte.com.tw) or contact your local dealer for the file.
If you want to realize the BIOS flash information, please refer to detail on subsection 5.1. "How to reflash the BIOS".
4. Troubleshooting Tips
The following troubleshooting tips may help if you experience problems. Contact your dealer or GBT for more advanced troubleshooting information.
■ Check that the card is seated properly in the AGP slot.
■ Ensure that the display cable is securely fastened to the card's display connector.
■ Make sure that the monitor and computer are plugged in and receiving power.
If necessary, disable any built-in graphics capabilities on your motherboard. 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 you selected the appropriate display device and graphics card when you installed the graphics driver.
If you have problems during bootup, start your computer in Safe Mode. In Windows® 98 SE and Windows® Me, press and hold the CTRL key until the Microsoft® Windows® Startup Menu appears on the screen. Then select the number for Safe Mode, and press Enter. (You can also use F8 to bring up the Microsoft Windows® Startup Menu.) In Safe Mode, bring up the Device Manager and check for duplicate display adapter and monitor entries if you are only using one graphics card.
For more assistance, use the Troubleshooting Guide located in the Windows® Help or contact your computer manufacturer.

If necessary, adjust your monitor's setting by monitor's adjust panel to make the screen looks focused, crisp, and sharp. (Please refer to the monitor's manual.)
