Samsung laptop randomly shuts down

Have you tried looking at SpeedFan? I use that on my desktop and it gives different internal temps

"Sorry to say this and whilst not a technical answer, it will resolve the problem:

Take it back, it is defective. I have used a few Samsung laptops and they are very reliable. This is abnormal behaviour and you shouldn't need to buy anything additional to make it work and run normally."

the problem with this is easily solvable :D... when you are playing from mains, remove your battery and the temp will go down, 15 degrees easy.

"This is really the best solution for such issue:

First you have to know that the problem is because of the NVIDIA Graphic software
you probably reinstall windows system and you don't have Samsung manufacture recovery . however the solution is regarding to the same description.

so how to be solved?
First, you need to uninstall NVIDIA from your computer.

Second go to http://www.samsung.com/us/support/owners/product/NP-Q430H
depend of your laptop Model mine was NP-Q430H.
anyway if you didn't register your laptop in Samsung official site you can do that anytime.
the reason why you need to do so is because to download the drivers matching your laptop.

Third, go to view all beside the downloads and expand the list-box, select the drivers option

Fourth,you will see a list of drivers. Pick the internal VGA drive and download all of other important drivers. its good to save them in computer so you can install them whenever you need them.

Note: after you uninstall NVIDIA THE SYSTEM ASK YOU TO RESTART WINDOWS DON'T YOU DO SO.

Finally install your drivers and restart WINDOWS and you will see everything is working wEll.

THANK YOU FOR WATCHING..."
