This has recently happened to me. Was playing fifa09 minding my own business and the screen froze. Restarted the console, reloaded the game, and then all i would see is the error message or a loading screen that went on forever

Phoned Sony and they said that my Blu Ray disc drive had died when the game had frozen?!?! They said it could be repaired but if that failed they would replace it! A courier arrived two days later to pick it up for repair and he returned with it today (9 days later)!!

Hooray!...HOWEVER...Hooked up the PS3 and it wouldn't start. On closer inspection, where they had taken the machine apart and put it back together, they had left a 5mm gap running from left to right where the top and bottom half of the console join and surprise surprise...it wouldn't work! Phoned Sony again this time a little miffed and they have said that a courier will return in 2 weeks!! to pick up damaged console and replace with another! Jeebuz!

I love my PS3 i really do...but c'mon! Feel free to phone Sony and get the drive replaced but don't relax until its back in front of you quietly kicking Xbox's bum!

Regards
