Hoping the problem is not hardware try using JSanders post for a reload.
If you recently added any apps one could be causing problems or even corrupted the OS. You can also use desktop manager (free at blackberry.com) to connect to the phone and see if it can be update using that software. The loader software suggested forces the update but if it's hardware it may be time to replace.
