Hi there
I'm having exactly the same probelm! If my Nuc (D54250WYK) looses HDMI connection (TV or AV-receiver shutdown) then my Nuc crashes immediately. I'm using the latest driver for Intel HD Graphics 5000.
I use the following adapters and components:
Intel® Centrino® Advanced-N 6235 (Blutooth, Wifi)
SanDisk X110 SSD 64GB 3.6mm
Kingston SO-DDR3L 8GB 1600MHz
My Bios Version is 2.8. Im running Windows 7 64bit Version 6.1.7601 Service Pack 1 Build 7601. PLease find attached my system.nfo for further information.
Thanks a lot for your help!
