AGP and DVI Adapter Cards

Dell™ OptiPlex™ GX270 Systems User's Guide

CAUTION: Before you begin any of the procedures in this section, follow the steps in "Safety Instructions."

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

Your Dell™ computer provides a connector for an AGP or DVI adapter card.

NOTE: The DVI adapter card works through your computer's integrated graphics. To control the adapter through your operating system, click the Start menu, click Control Panel, and then click the driver's user-interface icon.

1. Shut down the computer through the Start menu.
   
   
2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your computer, turn them off now.
   
   

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.

3. Disconnect any telephone or telecommunication lines from the computer.
   
   
4. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.
   
   
5. Remove the computer stand, if it is attached.
   
   

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.

6. Open the computer cover.
   
   

NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
