RAM Type

Hello, I am helping out my Dad with his computer which is running a bit slowly lately. He is low on storage space on his HD and can't correctly perform a disk defragmenter. I was hoping to persuade him to get another hard drive and update the RAM which ought to help him out. However, I am needing to find out what kind of RAM to get him. The information I found on the computer is as follows... Thank You.
