This was a bummer! I bought the NUC new from Amazon and it worked perfectly until last week. I have used the NUC very lightly since I received it near the end of March 2017. My NUC started freezing randomly. The freezing became more frequent until now I can't boot into any OS. I have tried to reinstall Windows, but am unable to do so as the computer will shut down or freeze during installation.Luckily Intel is working with me to send me out a new unit. I am just a little weary of the product now. I will update my rating if I have success. My main worry is that this will happen again in the future when I am out of warranty.
