PC Wierd crash help?

[IAmAkiro]

Okay I'll start with the specs

RM750X - GTX 1070 ROG STRIX O8G Version 390.77  GPU Version: - Ryzen 1700 Stock - MSI X370 SLI Plus - 120GB SSD Samsung 500GB WD Blue 7200 - G.Skill Flare X 3200 running 14-14-14-34 3200 on BIOS Version: 7A33v36.

Okay here is the issue. My PC earlier when I wasn't home crashed, both screens went black all light in my keyboard + mouse was out. i go over press on the mouse (Rival 700) it quickly blinks with some light but goes out again. I then check my PC there is light in my Ryzen cooler and in my GPU, so i wonder what the heck is going on, since this is only the 2nd time my PC crashes like this.

I have checked BluescreenView it finds nothing I don't seem to be able to find something in Eventviewer. I have uploaded Eventviewer screenshots with what there have been around when my PC booted this morning and till i came home and saw it has crashed. https://imgur.com/a/BwhXDpF

Also I am using High performance with Never & Never. 

Hope anyone can help me out a bit here.
