hey guys. i got an old ps3 for free from a friend that just got a new one, it just has a freezing problem. if I sit at the home screen for 10 min and then try and do something it freezes. also in games, it pops up with wierd colors in spots of the map. im looking for any help whatsoever. im more than willing to take the console appart if its necessary. if someone can point me to a video, that would be great. thanks guys.
