I had recently build my own pc with my friends and got everything new exept for RAM.
after about 3 weeks playing with it my pc stareted to randomly crash and then reset.
I was playing DayZ and i saw one of the major cities being rendered, and then my pc just shutdown and reset. I filmed this happening with my GoPro: http://www.youtube.com/watch?v=gSvR1wVC_tM and that is what happens almost every 40-60 minutes i have no idea what could cause this.

Hardware: motherboard: Asus Z87 Deluxe, processor: Intel Core i7-4770K, Watercooler: Hydro Series H100i, Graphics Card: Geforce GTX 770, PSU: Nexus RX-8500 850W, Not sure about the old rams, case: Colossus Venom, 4 fans, 2 HDD, 1 SSD and a bluray drive

if it is only happen when you are trying to play games there must some sort of conflict with your graphic drivers. is it onboard vga or separate one. did you update your graphic card drivers recently if it is tru try restoring your windows before that happen.
 
What temperature does the CPU reach when the shutdown occurs?

Do you have the discontinued four +12V rail model of the Nexus RX-8500 or the newest single +12V rail model? Nexus makes no claim of Intel Haswell CPU compatibility.

Is the graphics card using both hard-wired (6+2)-pin PCI-E cables from the power supply unit or are you using one of the (6+2)-pin hard-wired and one of the modular 6-pin PCI-E cables?

Im not overclocking cpu and its temperature gets max 60 C and i use the PCI-E cables from the powersupply not the modular ones and i had this problem with my older mpc which i took RAM from so could faulty ram be the reason?
