I would say that is is over heating, but when you play games it doesn't shut off. Remove the battery and run it only on AC power. See if the shutting down stops

I always use my laptop without a battery, if it is over heating why is it suddenly turn off when I first time turn it on and why is it when I playing that certain game my laptop won't shutdown. thanks for replying :)
