When I play RS in HD or Age of Mythology (similar to Age of Empire - same creators) my comp gets really hot and overheats then shuts down by itself. I have bought a cooling pad, which i put under my laptop and plug its usb into it, which makes a fan start to cool the laptop down. However, with temperature rising with summer, even when the fan is on, it sometimes overheat, so I have to be careful about that. :/
