Every time I play MAG (Massive Action Game) or Battlefield Bad Company 2 it freezes up. With MAG just before it freezes I lose audio and then it freezes up and with Battlefield Bad Company 2 it freezes up abruptly during games. I play on the original 80GB Playstation 3 and have been having this issue more and more within the past two months, first it started with BF:BC2 and now it's doing it with MAG every time I play. I think the system is over heating and yes I have it in a well ventilated area with a fan pointed directly at it but I don't have a vacuum as we have tile throughout the house. Everything else works fine though and it only freezes up when I play in online games... I'm getting frustrated and annoyed, very annoyed. I need all the help one can get with this issue! One more note, I clean all my games with a microfiber cloth before playing so I know they don't have any scratches on them or residue... PLEASE HELP!!!
