8GB Micron Memory
128 Intel SSD
My NUC is on 24/7 running Weather and IPcam software.
It has been mainly fine for a long time.
A week or so ago I noticed something amiss.
Upon checking the Windows event viewer I see that it is restarting up to 10 times a day.
Nothing else obvious is reported in the event viewer.
Enabled writing a system dump, but 'WhoCrashed' app never reports anything, no dump to read.
I disabled restart upon system failure to see if I could see anything on 'screen' ( I remote into it via AMT/vPro)
Still, the resets happen, I was remoted in when it happened and nothing, the screen goes black with no warning and system rebooted.
I looked in the AMT Event Log and notice this:
Operating system lockup or power interrupt.
It is reported every 2 minutes until a reboot.
Sometimes it will reboot again within 10 minutes, sometimes it will go a few hours.
Have done 'clean' boots into Windows to try and rule out software or drivers but nothing seems to make a difference.
Anyone got any thoughts?
Could it be Power Supply related? Memory?
I didn't make any changes around the time it started so I don't think it is software or driver related.
I suppose Windows could of updated, not sure.
Hello, paul_rickwood. Thank you very much for contacting the Intel Communities Team. I will be more than happy to assist you.
In order for me to assist you better, please provide me with the .txt file that the https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- System Support Utility will generate. To attach a file, you must click the "Attach" option on the bottom right-hand corner of the response box.
In addition, please share with me the part number of your RAM.
Thanks for the response.
The Memory Part Number is: 16KTS1G64HZ-1G6E1
The System Log is attached.
I did make 2 changes yesterday in that I changed the Windows Power setting to 'High Performance' and I also turned off Intel SpeedStep in the BIOS.
It hasn't rebooted since I did this.
The AMT Event Log still has Operating system lockup or power interrupt. every 2 to 3 minutes though.
I am now changing the Power in Windows back to 'Balanced' and see what happens.
Thank you very much for your reply, paul_rickwood.
I would like to know if after the changes performed the issue occurred?
Furthermore, please update your BIOS. Click https://downloadmirror.intel.com/27685/eng/RK0050.bio here to download the .bio file (0050) and, to complete the installation, please follow this guide: https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html
On a positive note, the crashes are no longer occurring.
However, there are still serious issues.
I can no longer use my external USB Harddrive. If it is attached then the system will not boot.
Nothing happens, the BIOS will not even start the boot sequence. It just sits there with the INTEL NUC logo.
This I don't understand, it used to be fine.
If I have already booted into Windows and insert the drive it is fine and I can use it, however upon a reboot it will not start up again (which is what I need as this is an unattended setup with daily reboots for stability reasons).
Also if I entered the BIOS Utility and then insert the USB drive it freezes the system and needs a reset from the power button (or via AMT web interface)
I also cannot update the BIOS.
Using the Windows Express BIOS update it says something about a non-supported legacy BIOS.
Using a memory stick/F7 method does not work as the memory stick is not seen by the F7 Updater Utility
Thank you very much for your input, paul_rickwood.
Can you please try performing a BIOS recovery? Please find the instructions in the following link: https://www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html
Please use the .bio file provided in my last post.
I was able to update the BIOS by ensuring that the Memory stick was slow formatted (not Quick Format) to NTFS. Then I was able to use the F7 method.
It still wouldn't boot with the USB Harddrive attached but I could get past this by changing the USB Ports to 'No Detect' in the BIOS.
So, for now, it is OK, it will boot and it is no longer crashing with the speed step disabled. I can live with this. AMT still logs the error every two minutes but it appears to be stable.
Thanks for your help.
