Please describe your system better. Provide full part numbers, not descriptions, wherever possible. What memory? What storage devices? What O/S(s) installed?
Thank you for your answer.
Windows 10 pro 64bits - 4Gb RAM
SSD Hard Disk Drive
Monitor: tv philips 43" Resolution : 1280 x 720 (I have tried different resolutions and the problem persists)
We need to know the part number for the memory SODIMM(s) that you have installed. For example, my NUC6CAYS has an Crucial 8GB DDR3L SODIMM installed whose part number is "CT102464BF160B.M16FN".
Thank you, that is what I needed to know -- and you are absolutely right; Google does a *horrible* job of translating Italian to English and English to Italian.
So, this tells me that you have compatible memory (incompatible memory is one of the things that might cause a delay like this). We can look at the next possibility.
Next, please tell me what version of the BIOS you have installed. The latest BIOS is version 50 (AY0050.BIO, AYAPLCEL.86A.0050.2018.0521.1533). If you do not have this version installed, you should upgrade to it now. Instructions for doing so can be found here: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005636.html Intel NUC BIOS Update Instructions. You can download the BIOS from here: https://downloadcenter.intel.com/download/27837/NUCs-BIOS-Update-AYAPLCEL-86A-?product=95078 Download BIOS Update [AYAPLCEL.86A].
Ok, the next thing to try is a 2-step process: (1) Clear CMOS (see http://www.intel.com/content/www/us/en/support/boards-and-kits/000005805.html Intel NUC Clearing CMOS for more information) and (2) Reinstall the latest BIOS release, but this time do so using the (highly recommended: jumper-based) BIOS Recovery process (see http://www.intel.com/content/www/us/en/support/boards-and-kits/000005532.html?wapkw=bios+recovery Intel NUC BIOS Recovery Update Instructions for more information).
Some additional notes on the BIOS Recovery process:
Hope this helps,
