It is probably related to the cleanliness (dust) of the cpu cooling system. When playing games or watching movies the cpu works hard and needs more cooling. If your cooling system is dirty, it could cause freezing of your screen. The video card needs also good cooling, check this also. Use a small vacuum cleaner or/and a compressed air can.
