Gen 2 X1 Carbon (20A7) freezing

[cjans]

Hello

I have a Gen 2 X1 Carbon which is attached to the OneLink pro docking station. The docking station has two Eizo CG 243W 24 inch screens attached.

Unfortunately, sinve about a month (and about two months out of warranty...), the system sort of freezes after it's been used for a few hours. The freeze looks such that the principal monitor goes black. The system still reacts to mouse movement, but not to keyboard input (ctrl-alt-del). I checked the various windows logs and cannot find anything wrong. 

I am suning Windows 10 (pre creators update).

Anybody have an idea what this could be caused by, any help greatly appreciated!

regards

Chris

I always suggest running a memory test first, although on this machine, memory cannot be replaced.

Look in the event log and see if a device is throwing an error.
