Problem: Your Playstation 3 console is freezing during gameplay. There are usually two problems that would cause your Playstation 3 to freeze during
gameplay. I will start with the most common problem:
1. The Blu Ray Laser is wearing out. This is a common issue among the newer video game consoles. The laser is constantly lighting up to read the discs while you are playing your Playstation 3 whether you are playing games, Blu Ray movies, or DVD movies. Eventually the laser will burn out. As it starts to wear out, first the games or movies will freeze. After a while, it will not read Blu Ray at all. Finally it will quit reading anything. You can find lasers at the following website starting at $49.95. The same website also performs repairs of the Playstation 3 console:http://store.richspsxparts.com/pl3paac.html
2. Overheating. This is less common. If your PS3 freezes and you shut it off and back on and it comes on ok, it's probably not overheating. If heat is the problem, it will freeze right away if you turn it back on right away without giving it time to cool off. If it turns on OK with no problem and doesn't immediately freeze up, the laser is your issue. If you turn it back on and it freezes right away, your PS3 may be overheating.
If your PS3 is overheating, the best thing to do is to make sure you do not keep it in an enclosed area. Playstation 3 systems and XBox 360 systems run very hot. You must keep it in the open so it gets as much cool air as possible! You can also upgrade the fan inside of your Playstation 3 with the Whisper Fan which increases cooling.
