My PS3 super slim wont play Skyrim but will play any other games

I have bought Skyrim for PS3 and plays fine for the first five minutes then freezes, if I restart my PS3 and try loading it will stay on the loading screen and won’t load the save file, I have bought two other copies from other game stores ie EB GAMES, VIDEO GAME TRADER, AND EBX and still the same result. All copies are in scratched, it plays any other game fine scratched or not, I am a major fan of Skyrim and need help
