Upgrading Your PC Memory

It was a tough experience for me when two of our PC's at home went so slow and couldn't hardly work for the internet. I got so bothered since I have lots of work to do online, so I requested a technical help from a computer specialist, only to find out that one of our PC's need to be upgraded with its system memory. Thank goodness for online stores which provide budget-friendly prices for PC memories. At least, I know where to get mine next time ;).
