Installing an expansion card is very simple.

1. Turn off the computer, unplug it, and take the case
   off.
2. >Find the slot that your new card will fit into.
   If you are installing an AGP card, then spot the AGP slot, usually
   the shortest slot and is brown. If you are installing a PCI card,
   then find a PCI slot, usually white and a tad longer than the AGP
   slot. An ISA slot is black and the longest on any modern
   motherboard.
3. Remove the dust cover on the back of your computer
   that is next to the slot you want. Don’t lose the screw; you can use it to hold the card
   in. Push the card into the slot you chose. You may need to rock it
   into place. Be careful not to damage the board by pressing two
   hard on an improperly supported motherboard. You may bend it.
4. Be sure of a few things. Check the card’s manual
   for any jumper settings or other information. This might save future trouble. Also, make
   sure that the shiny end with the connector faces toward the back of the computer. Don’t
   force it in. You might have to play with it a little, but when the card goes in, you’ll
   know. It will be snug in there. Make sure the card doesn’t touch any other cards. That can
   cause electrical problems, as you might imagine.
5. Secure the card in place with the screw.
6. Plug the computer back in, turn it
   on.
7. From here on, the procedure
   varies from card to card. The general idea, though, is that
   assuming the card is plug-n-play, Windows will detect the new
   hardware and open the Hardware Installation Wizard. Follow the
   prompts and have the driver disk ready.
