I have a Windows 2008 R2 Server that switchs off on his own. and it does not look like a hardware problem since I can see in the log how all services are stopped and after:

I have switched now from "Balanced" to "high performance" to see what happens.
This is the event sequence:

Before the UserPnP event, there is an event from 4 hours before. All those "7036" are "the XXX service entered stopped state"
Probably it does not explain anything, but this is the UserPnp event:
