One of the easiest ways to make your computer run faster is to add more RAM. The more RAM The computer has, the more instructions and data can be stored there. You can often add more to a computer by installing additional memory cards on the motherboard. Currently, you can buy 128 MB to 32 GB cards, and usually, you can add more than one card.
