Random Restarts w/ Boot Error message

[Caladir]

Good day every one. My computer is acting rather weird lately. I was sitting there drawing on the computer with my wacom tablet and it randomly black screened on me. After the post stuff, it said Boot Error. After this it restarts again and boots just fine. This is the second time this has happened to me.

My specs are....
i5-3570k OC'd @ 4.2 (and has been stable for over a year)
AsRock Z77 Extreme 6
MSI GTX 670 w/ No OC
Rosewill 550w Capstone semi-modular PSU
2x OCZ Vertex 4 126GB SSD's in Raid 0


Like I said, this error has happened twice now while doing two completely different things on the computer. This time there was no load on the computer at all and it happened.

According to this image I took my PSU seems to be operating normally.

I also ran chkdsk and it found nothing.

I also ran CrystalDiskInfo 7.0 and it said my SSD's are at 97% health.

Any further troubleshooting tips or ideas would be most welcome!

Was win 10 an upgrade from 7 or a fresh install?
If it was an upgrade from win Win 7 your bios should be set to legacy boot
If its a fresh install then your bios should be set to UEFI

Some BIOS have an auto setting which means they can switch between them on a restart, which is why your PC loads right on the restart - or that is my theory anyway.

It doesn't explain why it swaps sometimes. You might want to look in boot options and see what yours has there.

Fresh install and my BIOS settings are correct.

My issue isn't the "Boot Error" message but the fact that the computer will randomly restart out of nowhere under different loads and circumstances.
