Did you drop it or expose it to liquid or moisture? If so, hardware damage may be the problem.

Does the battery fit tightly in the compartment?

Are you using a genuine BlackBerry battery?

Do you use a memory card? If so, did you test with the memory card removed? A faulty card can cause weird behavior.

Did you install any apps immediately before the problem started?
