Siskin: Thank you very much for contacting the Intel® NUC communities. We are sorry to hear the NUC is not working properly.
In this case what we can try is a BIOS recovery to 0061 by removing the jumper:
Did you test the NUC on different outlets?
Did you try to disconnect and re-connect the HDMI cable, keyboard and mouse?
Did you test it just with one memory stick?
Do you have the option to test the NUC with a different power adapter?
Any further questions, please let me know.
