Greetings,I started having this problem.In the past,it happened few times,but now it is more frequent.I googled about it and people say that something probably overheated,but it is not in my case.My CPU is very cool,GPU in Witcher 3 doesn't get above 51-52C(using Xtreme Plus cooler),GPU VRM temp stays at around 60C while CPU VRMs didn't even get warm(put active cooling on them).People also say it could be PSU,but mine delivers somewhere around 11.78V on 12V(not the best,but deep inside the limits of -5%) but if that is the case I would get message on startup that PC turned off because of unstable power supply.I have quality PSU Silverstone 400W.Right now I am using HD 7870 XT,before I used more power hungry card,GTX 580 and I think this didn't happend so I don't think it shouldn be PSU problem.I am really out of ideas what it could be...Thanks in advance.

Yeah, as QSV said, 11.78 is not really good, not for a quality unit, I've had my OCZ 550w Fatality for 6 years already, still holding 12.10 to 12.17V.
Still, let's make sure what exactly is the cause, try stress testing your system with 3DMark or similar, monitor your CPU/GPU and PSU values with HWMonitor (enable its log feature) and lets see what happens right before the shut down.

I stressed it with Fire Strike and it did not shutdown.It happend before when I started Counter Strke:GO and now it is happening when I play Witcher 3.So yesterday when I started Witcher 3 I could play for around 10 minutes and then it shut off.After another startup I could play for around a hour and for the third time it shut down within minutes I got in game.Right now GPU-Z is showing 11.94V on 12V,will report you back how much it will show while playing Witcher 3.
Didn't run Prime95 for so long(my CPU draws max around 110W so it is not good for testing power delivery).Most GPUs will start to thortle on Furmark so no point of running it,I have seen most of my cards setting voltage at idle when I ran Kombustor(same as furmark).Right now it is staying at constant 11.75V in Witcher 3.
