I had an issue with my 40 gb ps3 clicking and not loading disks, took the drive apart and realigned everything and it seemed to do the trick, except after 10-30 minutes of playing the game it will freezeand cuase the system to shut down, after reboot it works again for a short period. Any suggestions of what may be causing this? Any suggestions or links are very much appreaciated, Merry Xmas!
