A very uncomplicated step.

• Find an expansion slot ideal for your video card. The slot must be the correct type, and it should be as far as possible from other hardware in the system. In most cases, you will be using the brown AGP slot which is furthest up, next to the processor. The newest form of video slot will be PCI express. PCI express can also be found in a dual card format called SLI. Wikipedia states “Scalable Link Interface (SLI) is a method developed by NVIDIA for linking two (or more) video cards together to produce a single output. SLI is an application of parallel processing for computer graphics, meant to increase the processing power available for graphics. With SLI, it is possible to roughly double the amount of graphic complexity that can be handled by a computer just by adding a second identical video card.”

• Remove the case back insert that corresponds to the slot on the motherboard. This is usually done by removing the top screw, but some cases have punch out inserts.

• Insert the video card in the slot. You might need to rock the card in, inserting one end first, then rocking the rest of the pins into place. The old AGP cards may be tougher because of their length and small hook on the rear of the slot. You might not be able to rock them. Most, though, will not be dealing with AGP video cards anymore. When pushing down, make sure the motherboard does not flex. If the board tends to bend, it may be necessary to place one hand underneath the board to hold it up. Also, in some cases, you may have a problem with the leading edge of the video card’s metal plate hitting the case behind the motherboard. The result is that it keeps you from being able to push the card in all the way. But, in most cases, just playing with it for a bit will do the trick.

• Screw the retainer screw back in place.
