What is a computer website that tells you about different models of computers?
As Jasper says, you're probably looking for crucial.com which is a website that advises on memory upgrades. If you're looking for any other upgrades, you should visit your computer manufacturer's website and search for the documentation for your model. HP, Compaq and Dell for example have user manuals and repair manuals on their sites that show you how to upgrade various parts on your computer.
Other sites include Tom's Hardware, which is very technical and probably not for beginners, and eHow.com, which has user written instructions on how to do most everything.
