To anyone wanting to upgrade the RAM in their machine I would highly recommend going to crucial.com. After searching quite awhile, I found their site. You put in the specs of your computer, it tells you what you can use, gives answers to a list of questions and sells the appropriate chips. Turns out that the first chip I bought from a seller on Amazon was defective. I kept the other new chip and put in one of my old ones and VOILA- problem solved!
Thank you, Baby Jesus!!!!
