After the last attempt i upgraded the firmware to 35.
Reset all to defaults and started again.
This time i installed all of the latest stable x64 Windows 10 drivers from the download center in case the issue was due to a missing driver.
Also used wired Ethernet instead of wireless for the hell of it.
Unfortunately the issue remains.
System is very cool here (Winter in Melbourne, Australia).
The fan spins up on start then relaxes to a low speed, temps at least in the UEFI config screen look fine, so i'm pretty sure overheating can be ruled out.
Previous HTPC lives inside the TV cabinet, this thing looks too cool to hide, so will live in the open air on top, 'tis in the middle of the lounge room for testing.
On a good note, with fast boot enabled the time from cold and dark to login screen in unable to be measured as it is faster than the time it takes the monitor to come out of standby mode.
For diagnostic resons fast boot is off for now.
Was going to screen cap and post the error in the event viewer but it froze, probably pointless anyway as it is just the generic 'did not power down correctly' message, with no prior issues before the shutdown.

I experienced this exact same issue. It has only happened once for me so far, but it was a complete screen freeze - there were a couple of things open that had progress bars going, for example (time based), and they quit moving. There was no BSoD, though. Just the "stuck" screen.
Yep, that's exactly it.
No BSOD, no warning, no alerts or sounds.
You just look up at the screen and realize nothing on the screen has changed in the last few minutes.
You go to move the mouse, pointer is frozen.
That's when you know the situation is so bad it wasn't even able to BSOD.
I have made arrangements to return this machine on the coming Saturday.
I can only assume there is no quick fix available, am kinda fond of the unit, if there is anything i can do whilst i still have it to make it work that would be appreciated.

Have you considered testing different RAM and SSD?
Try one memory stick at a time or if you have only one installed try it on each DIMM to try to isolate the issue.
Try installing the latest graphics driver, you can download it here:
Intel® Beta Graphics Driver for Windows® 10 and Windows 7*/8.1* [15.40]
I suggest uninstalling the old driver and reinstalling this one.
I know that this tedious to do or you probably already try this but I’m just trying to help you as much as I can, also I appreciate you have taken your time to report issues to us.
If you try all these troubleshooting steps and the problem persists please be aware that Intel provides three years warranty and if you need to replace the unit you can submit a warranty request at the following link:
Thanks for your reply Ivan.
I uninstalled the graphics driver and have installed the Beta driver, and the problem is persisting.
I have just been coming to and from the machine for the last 10 hours trying with different memory configs, 1 piece in lower slot, 1 piece in upper slot, alternate piece in lower and again in upper.
It did run for an hour with 1 piece of ram in the upper slot, but then froze.
Another disturbing thing i have noted is a 'clicking' sound in the audio.
Audio is from NUC to Pioneer VSX-921 via HDMI.
Still keen to get this going but i seem to have 2 issues now, system freezing and clicking in the audio.
It looks like i might build a mini ITX machine instead.
I'm in a position where i can't afford to spend more time on this issue.
Additionally if i hold on to the device i loose my ability to claim Dead on Arrival and get a refund.
The freezes in addition to the audio issues render the device useless to me, if i could at least get a blue screen or some useful info in the system log i'd feel like i have something to work with.
I do appreciate your assistance, and continued offer.
If the retailer is able to shed any light on the issue i will report here.
