Computer issues

Well, I have almost completely killed this computer. I have too much crap on it - kind of a theme in my life. I purchased an external hard drive - Seagate something or other. It's cool, but it came with no instructions and I am way too lazy to look it up on the Internet. By screwing around, I think I have freed up tons of memory. What does this mean? It means I will post pictures tomorrow. It is way to late to do that tonight.
