boss ur location?my ps3 slim 120g problem is:

-game disk took long time to enter into the game, can hear eject sound and it will stop loading afterwards,so i have to eject the disk and insert again and repeat these for more then 4 times
-playing Metal Gear Solid HD sometimes long last loading
-some games will auto shutdown within couple minute to half an hour

is it lens problem and overheat issue?how much will it cost?
