Adding memory is not difficult - for sure you can do it.

Make sure to buy the correct memory for your particular model of
computer. The major memory manufacturers, like Crucial (www.crucial.com)
have memory selectors that will show you the exact memory you need for
your computer. They will also have complete instructions for doing the deed.

Your owner's manual and your computer manufacturer's website will also
provide complete instructions, tailored for your model of computer.

Adding RAM was the first upgrade I ever performed on a computer. I was
real scared, because previously the largest upgrade I ever performed was
changing a light bulb. I succeeded and so will you. Just follow the
directions to the letter and take it slow. And don't buy RAM from places
like Costco or Walmart, and especially not on eBay.
