Laptop freezes when playing games

My laptop freezes a lot when playing games. It used to freeze when I had programs like chrome and skype up at the same time, but after doing a fresh reboot on the laptop, that problem went away. However the game freezing still persists. It'd freeze when I play Minecraft, sometimes freezing within 10 minutes. Games like Aion and such do not produce the same problem, I can play hours without a problem. It isn't a heating problem cause sometimes when I open Minecraft, the whole laptop would freeze within 20 minutes of playing.

My laptop is an ASUS, model K501UW Signature Edition running on windows 10 Home.

The specs are:

Processor: Intel(R) Core(TM) i7- 6500 CPU @ 2.50GHz 2.59 GHz
RAM: 8.00 GB
Graphics Card: NVIDIA GeForce GTX 960M

For clarification, when the freezing happens, everything stops, even calls. It won't do anything unless I forcefully shut it down. I've tried lowering the RAM usage of Minecraft but the problem still persists.

Can a gaming pc be use for digital arts?

I know this is a dumb question but i'm curious.I'm going to be building a computer soon because I like play Minecraft that would slow down time to time and I also want to play the older Tomb Raider games and Shantae. I would like to know if the art software that I'll be using are going to be too much for the gaming build to handle. The software that I'll be using are Manga/Clip Studio 5, Sketchbook Pro, and Krita.
