    NUC6i3SYH bios has detected unsuccessful post attempts, only on cold boot


      I am getting the "BIOS has detected unsuccessful post attemp(s)" error screen.. but only on a cold boot (first time powering up)..

      The NUC boots, the windows login screens comes up (doesnt matter if I login or not).. but after a few minutes (5-15) it crashes and shows this error.


      When I press 'N' to  cancel and attempt to boot with previous settings, it just runs fine without any hickups.



      - Intel NUC 6i3SYH

      - Kingston ValueRAM KVR21S15D8/16 (16GB ram)

      - Samsung 850 EVO M.2 500GB


      OS: Windows 10, x64


      BIOS: 0024 (shipped with) -> upgraded to 0039 -> upgraded to 0042

      The upgrades always went OK, no failures or issues.


      Installed the latest Chipset + GPU + WLAN + LAN drivers

      Disabled the Bluetooth


      Tests for stability

      - Intel Diagnostics (gfx): Pass

      - Prime95 for 3 hours: Pass

      - Windows Memory Diagnostics: Pass

      - HDTune: Pass

      - Samsung Magician: Pass


      After the cold-boot error + pressing 'N' it will run smooth for several days (3 consecutive days i have test).


      Please help !
