If you're not a Macintosh user, you probably have no idea what I'm talking about. If you have a Mac, then maybe you do. Apple computers have a small amount of RAM that stores basic setup information about the computer; it's called parameter RAM, or (go on, guess...) PRAM. Settings for the mouse, keyboard, startup, etc. are stored in PRAM. If PRAM gets corrupted, your Apple computer can crash or freeze. The simple steps to reset or Zap your Pram can resolve many problems on a Mac. Here's how to do it.
