Did you drop the BlackBerry hard shortly before this? Or get it wet? Those are the only possibilities that occur to me. See what others say. If moisture is a possibility, you need to remove the battery right away and dry the device thoroughly. And head over to blackberryfaq.com and scroll to the bottom for suggestions on how to dry it.
