Randomly Shutting Down

Hi. So i have been playing games and everything has been fine. BUT, for some reason why pc just shuts down (no bsod no nothing). It is very inconstant and will happen randomly. Some days it can be fine without it happening then it could just happen. The computer doesn't shut down in any other time.It mostly happens while playing fifa 14 (within 5-10 minutes of game play) while games like League of legends and ac4 on max settings doesn't do it. It has happened once on assassins creed black flag within 33 hours of game play

Here is the even log :
