my laptop shutted down by itself and it is not because overheating

[robertwt7]

so when i played CS GO, suddenly my laptop shuted down by itself. and i don't think i'm using nvidia geforce, i think my display is using the intel HD and can't be changed

here's one of my problem : http://www.tomshardware.com/answers/id-2221407/nvidia-geforce-gt540m-detected-screen-resolution-display-reinstalled-luck-nvidia-display.html#13743673

and right now after my fps reached around 60 and my core temp is at 70, the fan gone fast(like turboing) and my laptop turned off by itself. anything wrong?

Laptop make and model.

Got the manual? It should show you how to change from integrated graphics to discrete graphics.

Clean out your laptop. Remove what case panels you can and blow it out.

opened up mate, cleaned the dust, still it doesn't help me. i mean i use core temp app, and exactly before it shuted down 4 of my core was only 70 degrees, it just doesn't make any sense. really confused with this laptop

is there any other reason why a laptop could shuted down by itself?
