Firstly, ensure you PC is placed on a clear, flat surface with plenty of room. You should keep the power lead of the PC plugged into the wall, but with the power switched off. This ensures that there is a route to Earth for any rogue electric charges.

Next, remove the lid from the PC, still ensuring that the power lead is plugged into the wall.

If you have a Tower base unit, like this one, then place the base unit on its side. It is much easier to work this way. Users of desktop PCs to not need to do this.

We would strongly recommend that an Anti-Static Wrist Strap is used. This ensures that there is no electric charge passed to the electronic components that are being removed from the PC, as these will damage the parts and possibly render them unuseable in the future. As can be seen from the picture, one end plugs into a wall socket. The other end goes round the wrist.

Next, making sure that there is an available slot inside the PC to plug the hardware into, and that the blanking plate has been removed, lower the card towards its slot.

Once the card is touching the slot and is lined-up correctly, firmly push the card until it is seated firmly into the slot.

Next, tighten the retaining screw so that the card remains in place. The hardware is now installed. Finally, replace the lid, plug all the cables back into the PC and turn it on. In order to use the new hardware you might need to install new software, which would have been packaged with the card.
