D34010WYK Won't Boot

Hi,

I have an Intel NUC D34010WYK that I have just bought and have installed the following two components:

• Memory: 1 x Samsung 2Gb 2Rx8 PC3 - 10600S. Bought this from the following site https://www.mrmemory.co.uk/memory-ram-upgrades/intel/next-unit-of-computing-nuc/d34010wyk?search=D34010WYK
• WiFi: 1 x Intel Dual Band Wireless-AC 7260 PCI Express Half Mini Card. Bought from the following https://www.dabs.com/products/intel-dual-band-wireless-ac-7260-pci-express-half-mini-card-91MF.html

Both appear to be compatible but whenever I switch the NUC on I get the three flashing blue lights and then within a minute it restarts and does the three flashing lights again.

I thought this was a broken NUC so the supplier swapped it out for a new one but am getting exactly the same.

I have tried different memory in the unit because Intel say that the 3 flashing lights is a memory error but I get the same results.

I don't have a mSATA drive installed as planning to run everything from USB.

Am I missing something here?

Thanks.

Pete.
