I powered ON my BOXNUC8i3BEH for the 1st time. The power button LED flashes a few times then goes off, stays off for a few seconds, then flashes a few times then goes off, then flashes a few times then goes off, etc., etc., till I turn it off.

It still has no operating system. I'm awaiting for the BIOS to turn on the screen monitor and locate my DVD-ROM or SSD or USB memmory connected to a USB port. What can I do?

1. 3 blinks, On-off (1.0 second each) three times, then 2.5-second pause (off), indicates memory error.
2. Remove and reseat the memory.
3. If you have two memory modules, try using just one memory module at a time, swapping it between the upper and lower memory slots.
4. What is the manufacturer and P/N of your RAM?

Hi Leon,

Thanks very much for your reply.

I did everything that you advised but the problem persists:

3 blinks, On-off (1.0 second each) three times, then 2.5-second pause (off).

Hi Jaime,

1. The blinking you are seeing, indicates RAM failure or not compatible RAM https://www.intel.com/content/www/us/en/support/articles/000005854/mini-pcs.html
2. I don't have any experience with Super Talent memory. Although looking of the technical data of the modules you are using I can see that this SODIMM meets NUC specification requirements. However, both modules have failure or are incompatible to you NUC.
3. My suggestion is to check this memory in other computer and even better, if you can borrow SODIMM from other computer/laptop.
4. Safest solution is to replace this memory with memory tested and verified by intel for your NUC. Here you will find list of such memory modules http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&productName=Intel%C2%AE%20NUC%20Kit%20NUC8i3BEH

Hi Leon,

Thanks again. Finally I went to the dealer here in Panama. They replaced the memory modules with another brand: Kingston. Those allowed the NUC unit BIOS to open and recognize my SSD drive.

Unfortunately they coulnd't get OS (Windows 10) to operate, not only with my SSD but with some other SSDs of their own, which they use to test the hardware. Finally they sent my NUC unit back to Intel in the USA for revision. It's will return in good working order in about 15 to 30 days.

Hi Jaime,

1. So, I was right that the memory causes the problem.
2. Since the memory and the SSD is recognized in BIOS, without describing what you saw, I can't explain what was the problem that the NUC didn't boot with SSD that works in other NUC and has Windows installed.
3. In such case, could be that the Bios is corrupted in some way. I would start with Bios recovery.
4. In the Bios settings, Advanced > Boot > Boot priority was the SSD with Windows listed?
5. Did you try to boot into Boot Menu (by pressing F10)?

Leon
