The problem could be due to any of the following...
A memory issue: Have you tried the memory in both SO-DIMM slots? Does it make a difference?
Watch the blue LED on the top of the unit - is there a blink pattern during boot? 3 blinks means there is a problem with the memory - See http://www.intel.com/support/motherboards/desktop/sb/CS-034364.htm for troubleshooting tips.
Or it may be the system is overheating - see http://www.intel.com/support/motherboards/desktop/sb/CS-034326.htm for info about that.
Thanks Lois for your reply
So we can rule out a memory issue
- the NUC does not blink and just loads to a blinking cursor
- I have tried the memory stick in both slots
Regards to the cooling:
- I tried to follow the instructions but it doesn't even give me the opportunity to load into BIOS
I pulled the board away from the case and checked to make sure the fan is running, all seems to be okay, i also reset the CMOS but removing the battery, still no change..
Now found the problem:
Screen Resolution - Change the screen and it worked...
Was plugged into a LED TV Monitor - Plugged it into a normal computer LCD using a HDMI to DVI Cable and it worked...
