I got my NUC up and running for about 2 days flawlessly. Then it took a dump. I was in the middle of watching a video on XBMC when the unit rebooted. Since then it will reboot after about 3 mins being powered On. I have disconnected everything (including SSD) and boot to bios with the box opened and it will reboot without warning. I checked the AC adapter but it's output seems to be within acceptable range. I don't want to return the unit but I will.
It seems after awhile of cool down it runs for about 10mins and then does the reboot thing again. The bios temp doesn't read more than 45°c each time.
