In the last few days I have noticed my PC would shut down in a instant when I'm playing higher demanding games (Crysis 3, Witcher 3 etc) from anywhere ranged 10 - 40 minutes of gameplay.
This doesn't occur if I'm playing SIMS 3, counter strike GO, Bioshock, Skyrim etc or any older game that isn't graphically intensive.
Could the issue be my current CPU or GPU? The AMD processor does have turbo boost and I did noticed the clock speed would go higher, I can hear the fans get louder as well. I know that my video card is drawing power from the motherboard itself so I'm not sure what else could cause the random shutting down.
Any suggestions would be appreciated.
