5 min into a game and the sounds goes then freezes

May sounds like a silly answer, but, do you have your PS3 hooked up to the internet. If not, there are many updates for the system which you are missing and therefore the new games will not play because of missing system updates. Hope this helps you out.

Upgrade to the newest firmware, since 3.0 had some freezing issues with some games, if your internet connection is slow it would also cause it to freeze up

Your PS3 is not correctly loading his firmware, if its new, bring him back and say what happened.

Try using a can of air to blow out the fan area. Even though its well ventilated it may be full of dust. It sounds like an overheating issue. Also look into aftermarket fan/cooling solutions, that dont plug directly into the PS3 and have there own outlet power plug.

The game miht be to warm
