i'm using G53SX laptop, it will randomly freezes when i playing games like Dota2, Diablo 3 or Mass Effect 3, but i still can move my mouse while it freezing. i can't ctrl+alt+del, alt+tab or alt+F4...turn off power to restart laptop is the only way. If i press ctrl+alt+del to go out, my keyboard and mouse will be freeze as well. It never happen when i play BF3 or Crysis 2... help...T_T
