My ps3 loads to the start up screen then freezes?

May be...

my ps3 gets to the sony entertainment presents screen then goes to the waves and freezes. I dont know whats wrong with it, it was working fine yesterday.

youve got the WOD (wave of death) just ring sony and tell them your problem, they will send you a box to send your ps3 to them in and then they will try and fix it. if they cant do that then they will send you a brand new one. usually they will send you a couple of games and an extra controller for your trouble aswell. hope this helps.

it could be broken inside and you got to go to game stop where ever you got fix it there
