Hi emir, Overheating often causes the symptoms you describe. However as little is known about your hardware there could other possibilities. May I ask.. . What is make/model of your laptop and charger? How old are they? Are all leads firmly inserted? . Does the machine shut-down only whilst playing games? If so, which games? . Does the machine feel very hot when not playing games? . Do any fans ever make strange grinding/clicking noises? . Is the machine used in a well-ventilated area? Have you tried using it in a cold environment? Thanks.
