Before you begin

  • Turn off the computer, disconnect all cables, and transfer 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.
The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.
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.

For best quality on dial-up connections, wait until the video has fully loaded before viewing.

Step 1: Preparing the PC

Before starting, if you are adding an expansion card that will replace a function that comes from the motherboard (video, sound, network), disable the on-board function and select the correct BIOS setting in BIOS Setup before attempting to install the new card. Do so as follows:
Step 1. Turn on the PC 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 possible selections for an award BIOS are:
  • Video: Primary Video Adapter
  • Audio: Audio Codec
  • Network: Onboard LAN
The selections on your PC may not be the same as those given as examples If this is the case, the selections will be very similar. Select the setting that most closely matches the type of card you are installing.

Step 4. Press enter 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: AGP, PCI or PCI-E depending on the type of video card you are installing.
  • 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 a network card. This disables on-board LAN, helps prevent conflicts, and saves resources for your new card.
