Welcome to the BlackBerry® Support Community Forums.
Have you re-inserted the battery? If yes, I would suggest backing up and doing a clean reload of the BlackBerry device software as shown here: http://btsc.webapps.blackberry.com/btsc/KB11320. Please test before restoring any data to the device.
If the issue still persists after the reload, further investigation might be required. To help further diagnose the cause, contact your wireless service provider or BlackBerryTechnical Support Services for further review and support.
