Return of Reckoning

The first time I tried to queue for scenarios, I got the notification to join, and as I thought the game was loading to the scenario, my computer restarted. I have since played a bit, and successfully got into scenarios, but the following night around the same time of night, my computer against randomly restarted while I was playing. I called it night, and this morning tried to log in, and had the game again restart my computer.

There is not blue screen, or error message. Just seems like a moment where you may find a black screen for loading, instead of a new screen loading, I get a monitor going to sleep message, followed by the Dell boot up screen. I run very little on my computer, but am open to ideas or fixes, or suggestions on interfering programs. I found it unusual that the game itself isn't just crashing to desktop or like, but the computer restarts. Windows 10.

Thanks for thoughts and ideas!
