Most of us are thinking to upgrade our computer memory; it is the cheapest solution than to buy a new PC or laptop. I am doing a memory upgrade on my personal computer, I noticed that the download is a little bit slow already and my computer is only 3 years old. I am sure it's not virus that causing it to slow down, because it is well guarded from viruses and malwares. My cousin told me to upgrade its memory; it's like adding life to your computer.
