It is important to remember to shut down the computer and unplug all the cables that are attached to your computer before doing anything else. Once this is done, open the computer case and touch the internal metal frame to ground yourself. This is a good thing to do with any electronic component to prevent destroying your expensive components and in this case from electrifying the internal components of your computer.
If at this time you find that you will need to remove one of the old RAM chips before you can install a new module. Just make sure you press down on the clips that lock the installed RAM chip into position, and the module should release easily from the slot. To insert the new RAM chip, gently push the module straight down into the memory slot. Just make sure you place your thumbs at the ends of the RAM chip to apply an even amount of pressure so both ends go in at the same time. The arms of the clips should return to a flush 180 degree upward position and lock the new RAM memory chip securely into place in its slot.
After this all that is required is that you put the computer’s outer casing back on the way you took it off and then reattach all of the computer’s necessary cords to the right slots. At this time you should, of course, restart your computer to make certain your PC's BIOS (basic input/output system) detects the newly installed RAM and the appropriate amount of RAM that you just installed in your computer.
If installing more RAM doesn't give you all of the speed you are looking for then you may want to invest in a new graphics card to relieve the processing load on the main CPU.
