I have NUC 8109U BOXNUC8I3BEK and recently the computer started to shut down randomly.
I have the latest drivers updates including the last BIOS version 0078.
I tried to run Intel Processor Diagnostic Tool and the computer shut down when it arrives to "Prime Number" test.
someone knows what causing the issue? is that operation system issue?
Hello Leon - thank you for replaying.
I download the app and ran it.
at the beginning of the test I used https://silver.urih.com/ site to stress my CPU and the temp raised to 84 deg' max.
but the average was 52 deg..
Please see the attached log.
all the steps were done but issue still exist.
My indication of knowing if the problem still exists is to run IPDT, and if it's still shut down my NUC during the "Prime number" test, it's mean that my issue still exists. I also have security camera software that worked before, and when I'm lunching the software, it's shutting down the NUC.
BTW, I update my BIOS version just recently... maybe it's BIOS version bug or something with my OS?
I update my BIOS via Bios Recovery - issue was still exist.
I also formatted my NUC now to Windows 10 and removed everything - a fresh windows installation from USB, I let the Windows to finished download and installed all the updates (including drivers) - and the issue still exist.
I think it's an hardware failure with my CPU or i don't know maybe one of the memory slots/motherboard? the thing that this NUC is very new and almost i didn't turn it on. I still have warranty and i will tell them to check the IPDT by them self and see that the test crashed during "Prime number".
Sure you can downgrade your Bios to the previous version. Please use exactly the same Bios Recovery from Power Button Menu (as described in my post above), except that use BE0077.bio instead of BE0078.bio
