NOTE: NEVER use a magnetized screwdriver during installation.
Remove the expansion slot cover from the computer case. (See Diagram A below).
Expansion Slot Cover Removal
On most motherboards, the PCI and PCI-Express slots are usually white in color with the latter being a little over an inch in length.
Due to the heat generated by the video card, place the sound card in a PCI slot away from the video card if possible.
The card and the slot are keyed so it is almost impossible to insert the card incorrectly.
Install the card in the PCI slot. Press down firmly and evenly across the top of the card until it is securely seated in the PCI slot taking care not to damage the card or the slot. (See Diagram B below).
Sound Card Insertion
Secure the sound card to the computer case using a small screw. (See Diagram C below).
