First remove the battery and leave it out for at least 5-10 minutes before restarting. Also try restarting without the memory card and sim card.
Once you have your phone switched, then you can easily update the phone firmware using Nokia Ovi suite or Nokia Software updater.
If you are unable to switched your phone then I think the only way is to contact with your nearest Nokia care to fix the problem.
You can get some FAQ here: http://europe.nokia.com/support/download-software/
