Intel NUC randomly shutting down

I purchased a new Intel NUC 10i7FNH4 recently and it is randomally shutting down for no reason.  I have tried updating to latest bios and updating the drivers.  I also double checked that the ram and hard drives are correctly connected.  I have also set the fan profile to Cool in the bios.  I installed a program to check the core temps and all seems fine.  Any suggestions?

It's usually spontaneous resets if bad memory, but it is still a possibility. I suggest you download and run MemTest86 for a few hours and see if it finds anything.

The memory test didn't reveal any errors.  And problem is persisting (in fact sometimes it wont even start when I turn it on (after it has randomly shut down) unless I unplug the power cable and plug it back in.  Anyone else with a suggestion?

So, based on that, two possibilities come to mind:

  1. You have a part, somewhere in the power circuitry of the NUC or in the Power Supply (PSU) itself, that is starting to fail. When it gets hot enough, it trips the NUC's power. Disconnecting A/C power would give it enough time to cool off to point where it works again.
  2. You have a ground loop forming. Disconnecting A/C power would kill the ground loop for a while.

For either of these problems, you likely need to replace the unit or its PSU. If you are still within its  warranty period, I would say that it is time to contact intel directly and get this unit replaced.

 

After verifying that your warranty is still active (here: Determine if Your Product Is Still Under Warranty), you need to directly contact Intel Customer Support to initiate the RMA process (you cannot do this through the forums). Here are pages where you can lookup contact information, including local/country phone numbers, by geography:

You can use the online forms service or email, but I actually recommend calling them directly. The above links provide local or toll-free numbers in most countries and support most local languages. You could also use the chat service (start here: Intel Customer Support Chat), but understand that this service is offered in English only and is subject to the normal (9:00-5:00 M-F) office hours in the Pacific (UTC-8) time zone.

Hope this helps,
