Here's what I think I learned from my individual defragmenting experience: Everytime you visit a website, it takes up a minimal amount of space in your computer's hard drive. However, overtime all that space can add up, filling up your hard drive and thus making your computer slower. This is especially true for websites like these that have cookies and caches that remember your passwords and everything. Programs such as IE and Microsoft Word also take up some space. When you defragment (actually, we did a lot of things, so it probably wasn't just the defragmanting) you are, in essence, cleaning your hard drive and wiping it free of all that space by condensing everything you have into a smaller space. If you haven't done it in a while, this process can take a while, so I recommend you do it overnight. Afterward, you can just start doing regularly and you will start to see faster results in your computer's efficiency. Doing this won't necessarily solve all your problems, but it's at least worth a shot. I would hate to see you leave. ;_;

P.S. There is a possibility that there is also a virus in your computer that is taking up all the space (that was our issue). We had to call tech support and this Indian dude (not being stereotypical, he was Indian. xD) knew just how to fix it. I would highly advise that you try that, as well, except it can be quite costly and time-consuming.

Hope all this helped! This whole ordeal happened to us on Christmas Eve and we learned a lot from the experience. xDDDD
