After adding one, I found out that when the display goes to sleep, Windows sees it as a disconnection, and 'helpfully' wakes up to reorganize all the windows onto one display. That wakes up the Display port monitor, which triggers another reorganization, and the cycle begins again.
Googling didn't get me too far obviously.
I ran into this after building a system and it was very frustrating. IIRC my problems were related to my network card and having virtualbox installed. Also turning off wake for my mouse helped (bumping the desk would turn on the computer).
Wasn't any device, like network adapter and power diagnostics returned nothing.
Solution: reset motherboard NVRAM. No more mystery wakeups!

1. The start menu latency is now so bad you have to forcibly wait 2-3 seconds before typing your search after hitting the start button. This is on a stacked E5 Xeon workstation class machine.
2. Search is crap. I can type "visual" and visual studio doesn't come up!?!?
Some of the problems I understand; “regedit” has to match exactly because it’s basically doing the “run” dialog box. But no idea why other stuff can’t be searched for.
Thanks svchost.exe!
I disabled updates, but it still does... something while I am sleeping.
