Nokia 6600 Problem

Problem:

I have a Nokia 6600 and I have a problem starting it up
everytime I switch on all that happens is the Nokia logo
appears and disappears about 4 times then it switches off
I cant even switch it off myself when it is trying to start
up.
Can anyone please help me with this problem :

Solution:

1. Try to boot up in safe mode without MMC....
   
   If it doesn't help u than proceed with three key boot up format trick, u
   will loose all user data but u will get back your phone...
