Ok so I was playing call of duty and the game froze so i restarted my playstation 3 but when i went to pick the icon to start the game it wasn't there. So i took the game out tryed several times with other games but still the same results. So basically i'm asking do you know whats wrong with it or has this happened to you and how to fix it, Thanks.
