Hello,
i have have my PS2 for a long time now and it is the old black one. I got a new game for my ps2 (fifa 06) and played on it for a while, i then lent it to my friend and when i got it back the disk was scratched to death. So i put it in my ps2 to see if it worked fine and it did so i paused it and went downstairs for a few hours, went upstairs and the game had froze. I reset it and it didnt read any game i had, i have even took it apart and cleaned it with air in a can and it made no difference. I personally think it is something to do with the laser but there have never been any problems with my ps2 before.
Anyway id appreiciate it if someone got back to me

thanks, Mike
