My laptop shuts down for no reason

I have G50V notebook pc. It shuts off itself I tried to turn on again. it does not work. Previously, it was shutting down repeatedly when the fan is hot but I turned it on again when the fan got cool. but now it is totally shuts off. what shall I do?
 
Sounds like the CPU is not getting cool or something else is wrong. take out battery. wait 30 minutes use the AC to turn on the laptop. Did it turn on?
 
Sounds overheat for me..

Based on my personal experience, this kind of symptoms also happened to me when I'm using Asus W7J..
I suggest bring it to service center, I hope your CPU/GPU not get fried because of overheating
