One of the easiest things to do is install desktop memory. To put in a stick of RAM, look at the center of the slots and you will see a notch. On the ends of each slot you will see a small latch. Pull them down if they are not already.
Next, look at the memory and notice the hole in the connector.
Place the ends of the RAM into the ends of the slot. Make sure the hole is over the notch. Push down on the ends of the memory until the latches on the slot attach themselves to the sides of the memory. You will hear a click when this happens.
That's all there is to it! When handling memory, try not to touch the contacts on the bottom. If your system supports dual channel and you want to use it, check the documentation to see which slots to populate.
