My ps3 froze its 4th time earlier just now before I posted this thread. I was playing ridge racer and when I got a new car, it just froze and I could still quit the game as I have mentioned ealier. I can't recally if I was pressing the buttons quickly hoping to get pass those screen. I'm wondering if the heatsink on the VGA chip is not properly sealed with heatsink compound...or it just doesnt quite like quick response when processing stuff. Gotta do more test and figure out the symtopm.
edit: I doubt it has anything to do with the firmware, mine is 1.31.
