Tell us about yourself!
For your information, the reason I upversioned to Win 10 was in the hope that it'd remove this issue. It didn't. I have found that different NVidia drivers create different logs in the Event Viewer. The latest drivers seem to simply show that a reboot has occurred. The older one that I use, and which is less susceptible, did at least mention it was Nvlddmkm. Now I have to assume it still is as the symptoms remain the same.
