The Audio stops when playing a game.

So I have the MSI GT70 2PE Dominator Pro. I bought it 1 year ago. Had no problems until yesterday. So I was playing Batman Arkham Knight and after 5 minutes of playing my audio stopped. I restarted my laptop and the problem was gone. Opened the game and the same thing happened. I tried to play another game. Same thing happening over and over again. So I realized that when I quit the game(doesn't matter which one), I wait about 1 minute and the audio comes back. I also have an extra fan, which I can turn on while playing when my laptop it's overheating.(doesn't seem to overheat, but whatever). I tried turning it while playing and the audio came back. So the conclusion I made, is that when my laptop ''heats''(overheats) my audio disappears. I tried installing the newest drivers, but nothing changed. What should I do?
