My playstation 3 keeps on freezing when i try to play any game?

May be...

it started about last week when i tried to play a demo and it just turned itself off. i dont know whether this was due to overheating or just something wrong with the ps3. i have now moved it into an popen space and put a fan around it but that doesnt seem to do much. HELP?!

sounds like you're gonna have to call sony to get this one fixed as you've tried most of the common fixes around, have you tried to hoover it out? take your hoover to the air vents to see if you can move any dust that may be in there. Your last option is to reset your machine, google it or look-up your instruction manual on how to do this because i've never tried to do it so can't guide you step by step...

good luck :)

Contact Sony directly, but don't mention that you think you may have overheated it.

Just tell them what is happening step-by-step, and see what they come up with.

Return that ****.

try faping on it

trade it in and buy a 360
