You know who you are. You own a computer, use it for email, surfing the Internet, and paying bills online. But when the bleeping machine freezes up or won't turn on it might as well be a nuclear reactor in terms of understanding how to get it going again.

Well, you've come to the right place to at least gain a fundamental knowledge of where to start, where parts are and what they do (in case you have to talk to some know-it-all squad of geeks), and how to do some basic things to keep the infernal device that seems to own big parts of your life operating as you expect it too. Remember, it's not a toaster.
