Visit a Samsung Service center. Looks like it's a hardware issue.

Hi, we suggest you to check for heat issues on notebook PC.

Step1: Check the vents.
•Inspect all the airvents on the computer. Remove any dust that may be clogging them. Make sureno skins, stickers, sleeves, etc. are impeding airflow.

Step2: Unplug the charger.
•Charging a batterywill generate heat, and can cause overheating if the computer is in heavyuse while charging.

Step3: Put your notebook on a table or tray.
•Notebook PCs aredesigned to be used on a flat surface to allow for airflow around the chassis.
