Adding or Replacing an Expansion Card (Video Card, Sound Card, etc...) in HP Pavilion Elite Desktop PCs

This document pertains only to HP desktop computers with the following types of computer case:
Image of the computer
Before you begin
  • You need a flathead screwdriver. Note that you need a screwdriver with a long shaft when you are replacing a long graphics card.
  • Remove the Pocket Media Drive, if it is present.
  • Turn off the computer, and then disconnect all cables. Disconnect the Ethernet or modem cable before disconnecting the power cord.
  • Move the computer to a clear, flat, stable work surface over a non-carpeted floor.
  • HP strongly recommends the use of an anti-static wrist strap and a conductive foam pad when working on the computer.
  • Do not remove a component from its protective packaging until you are ready to install it.
  warning:
The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.
  caution:
This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a noncarpeted floor, use a static dissipative work surface (such as a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.
Step 1: Preparing the computer BIOS
Skip this step if you are replacing an existing expansion card, and continue with Step 2: Removing the retaining bracket and/or an expansion card.
If you are adding an expansion card that replaces a function that comes from the motherboard (video, sound, network), before attempting to install the new card, use the following steps to disable the on-board function and select the correct BIOS setting in BIOS Setup.
Step 1
Turn on the computer and immediately begin pressing the F10 key repeatedly until a BIOS Setup screen appears.
Step 2
Press the Right arrow key to select the Advanced page.
Step 3
Find and select the setting that matches the type of card you are installing. Examples of what to select for an award BIOS (the BIOS on your computer may be different):
  • Video: Primary Video Adapter
  • Audio: Audio Codec
  • Network: Onboard LAN
Figure : On-board Video example

Step 4
Press Enter on the keyboard to open a list of options for the selected function.
Step 5
Select the option that best applies to the expansion card that you will be installing. Examples of what to select:
  • Video: PCI-E
  • Audio: Select disabled if you are installing an audio card. This disables on-board audio, helps prevent conflicts, and saves resources for your new card.
  • Network: Select disabled if you are installing an network card. This disables on-board LAN, helps prevent conflicts, and saves resources for your new card.
Step 6
Once you have made your selection by pressing the Enter key, press F10 to Save the settings and exit.
Step 7
Wait while the computer opens into the operating system (Windows). Once Windows fully loads, shut down the computer from the Start menu.
Step 2: Removing the retaining bracket and/or an expansion card
Use the steps in this section to remove the retaining bracket from the computer and to remove an existing card. You must remove the bracket before you can remove or install an expansion card.
