[gueco]

I am using 3 screens on my laptop, one of them with a displaylink adapter. When the PC boots all looks fine and I can use them for hours. But sometimes without warning the 3 screens become black and I have to do a hard reboot. Usually this happens during the night when the pc is idle. I had no problems whatsoever before the upgrade to windows 8.1.

Here are my log files in case it helps to solve this weird problem.
