My PC keeps crashing when playing games. It only seems to happen when I'm doing an action. Ex : I launch the game, everything is fine but when I click on a button of the menu, my pc crashes. When the PC shuts down, the fans accelerate. Everything is still on (keyboard, mouse, speaker...)
but my monitor is off. When I try to reset it, the vga led flashes three times. It takes usually between 1 and 2 minutes for my computer to accept to restart. The temps of my cpu and my gpu seem fine. The crash happens more and more often.

Configuration :
i5 6600k
R9 fury
16gb ddr4 3000mhz
Evga supernova nex 750w 80+ bronze
hyper 212 evo
Msi z170 sli plus

Sorry for my bad english this is not my main language, I've tried my best to be as clear as possible. If you have some question, don't hesitate.
 


It did not BSOD. In the event viewer it says : The system restarted without stopping correctly. This error can occur if the system stops responding, has crashed, or is no longer powered unexpectedly. Source : Kernel-Power.
