i used to play my ps3 often because it was fun. it still is but after i play it for 15-20 minutes it irritates me because it freezes. once this happens i have to wait at least 20 minutes to try and play it again. i think it may be because of update 4.31 becase before i updated to this software my ps3 never froze while playing a game, but the strange thing is it only freezes when im playing on game disc. CAN I PLEASE GET SOME HELP?????????????
