Oki I own a 80gb phat ps3 that is 2nd hand iv upgraded the hard drive to 160gb thats out of an old laptop
my problem is when i play some games it freezes and will not respond not even to the hard reset i have to swicth it of from the back, it mostly happens on fallout and fallout new vegas, vikings and once on AvP
my ps3 is well ventilated, it is cleaned once every 3 to 4 weeks.
Any ideas i kno this sounds daft but could it be my hardrive since it is old
