Computer crashes when playing games after 15-20 mins. Need help diagnosing.

Essentially I can be playing a match of Overwatch or a game on Steam, and after a while both of my monitors will go black and show no input.

- This has happened about 7-8 times over the past few days.
- During some of these crashes, the sound cuts out, but during other crashes it keeps playing.
- I am not sure if the computer is still responding to keyboard commands because I can't see what's happening.

The Windows event viewer shows the following:

As you can see, it's consistently the same error (Kernal-Power event ID 41).

My instincts are telling me this is a graphics card, power supply, or power distribution issue, but I am not savvy enough to confirm/diagnose. Anyone have any ideas?

I recently upgraded my video card and my ram, so that could be the source, but I haven't seen any temperature issues and my power supply should be able to handle the loads...

Processor: Intel i7 3770k

Motherboard: Intel DZ77GA-70K

Video card: Gigabyte GeForce GTX 1070 G1 Gaming

RAM: G.SKILL Ares Series 32GB (4 x 8GB) 240-Pin DDR3 2133

Power Supply: Cooler Master RS-750-ACAA-D3 750W Bronze Plus

Any help would be greatly appreciated.

    i tried looking around it might be power related issue:

    any overclocking done? cpu or gpu or both. does your RAM running XMP profile or just run at default setting?
