Hey guys im new to this site but I got a playstation 3 2 weeks ago and Killzone 2 now the problem is during killzone campain mode after playing for an hour the game will freeze and the controller will not work as long as the screen being frozen a manual restart of the system is required. So i thought it was maybe the game disk so i returned that for a new one and it has done it again once. It seems to do it when the game is loading between levels or autosaving. I dont think that there is anything wrong with my ps3 cause its brand new but what could it be. also the ps3 is on top of a table so it has plenty of free air to breath. THanks responses will be much appreciated, Chris
