Computer turning off during certain games

Hey, I'm new here, but I have been having trouble with my computer.
Before I start, here are its specs:
CPU: Intel i5 3570k
GPU: GeForce GTX 660
PSU: Seasonic 850W
RAM: Some generic DDR3 RAM I'm too lazy to look up
I built it a little over a year ago and until recently it worked fine. Maybe a month ago or more it started doing this thing where during a few specific games the computer would play it smoothly for about 10-20 minutes before turning off and causing the fans to go to 100%. The weird part was that the games that did this weren't much worse for the computer than the other games that didn't. Also, this computer was able to run those games easily for a year. I fixed that problem by replacing the thermal paste and CPU fan and getting new graphics drivers, but now the problem has returned in a different variation. The computer will play almost any game smoothly easily, but even when it's going smooth, after a while it will just turn off.For example, I just started playing Smite. The game worked for almost an hour before the computer just turned off. The fans didn't turn on like they did before; the computer just turned off.
I have researched this but still haven't found a solution. Do any of you know how to fix this?

    could be two issues. one the gpu fan is not spinning up under load and the gpu is over heating. try using msi afterburner check that the fans will spin up to max speed. in msi change the fan profile to max out at 50-60c. the other issue could be the power supply not holding up under load or the fan to the power supply not moving and the power supply under load is over heating and shutting down.
  2. Do you have another PSU to test on? If you don't how much RAM do you have? Because if you run out of RAM memory to load things in, or render things, you may crash.
