Windows 8.1 upgrade crashes screens

[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.

Hi,

Thanks, I've raised this internally.

Thanks,
