Laptop Shuts down when playing games

When playing games like warframe my laptop will suddenly shut down without any warning.



I recently reset my computer because it wasn't working properly and sleep mode was screwed up.

The laptop is running faster now but all of a sudden this problem appeared.



Before the reset and when it was working fine I could play games like warframe and blacklight retribution but now when I try to play them I can for a little bit with no lag and no overheating (I checked, everything is at around 50C after shutting down and instantly rebooting.)



The computer started slowing down and overheating so I got a cooling pad and reset the pc with windows reset feature and reinstalled all of my programs (Steam, Skype, avast!, etc.) and tryed playing Warframe and it was working fine. The laptop wasn't hot, it was running fine and then it shut down, for absolutely no reason!



Can anyone help please?


Please help.

Thanks!



I didn't find the right solution from the Internet.
