You are bootlooping. Have you rooted? If you are still stock, then some how or another where the files are put to tell the system what order to load them in got screwed up (probably by an over the air update). If this is the case, take it to your carrier's store. It's a warranty issue.
If you are rooted, find a good ROM assuming you have a CWM Kernel and CWM on your tab) and flash it. If you are rooted, and don't have CWM, then get one that is an Odin file (or Heimdall) and flash it that way.
If you aren't rooted, and haven't the faintest clue what I'm talking about when I say CWM Odin, and Heimdall, then follow step one, get a new one, and continue to enjoy.
