Thank you for contacting the Intel community.
You can try unplugging the NUC, remove every component attached to the unit and then plug everything back on.
Once that is done see how it goes, if it doesn’t work try the following:
Do a clear CMOS to the BIOS; please follow the steps to clear CMOS.
- When the Intel NUC is off, press and hold the power button for approximately 3 seconds and then release. The Power Button menu should appear.
- Press F2 to enter Intel® Visual Bios.
- Press F9 to restore BIOS factory default values.
- Press F10 to save and exit Intel Visual BIOS.
Once that is done you can set any configuration in the BIOS as you had it and see how it goes, if it doesn’t work try a BIOS recovery.
Please see BIOS recovery instructions and you can do the BIOS recovery to the same BIOS version 0365.
Please let me know if that helps.
Thank you for the reply.
I carried out the first two steps to unplug everything and reset Visual BIOS back to factory defaults, but then decided I'd just go the whole hog and recovered the BIOS to the same BIOS version.
I'll see if the issue re-occurs over the next week or so during normal usage. It's Patch Tuesday on Tuesday so I'll see how it is after that, as that's usually when I notice it happen.
