I recently bought parts from Amazon to build an embedded PC, and have assembled everything. I have:

• Intel D2500HN Mini-ITX Motherboard
• Mini-Box Pico-PSU 80
• M350 Universal Min-ITX Enclosure
• 2GB DDR3 Memory
• Kinamax AD-LCD12 LCD Monitors 12V 6A 72W AC Adapter Power Supply

The motherboard gets a light (on the motherboard, not on the Pico-PSU) when I plug it into the power adapter. Furthermore, I see the power switch light come on when I press the power button. However, the display doesn't turn on, and it doesn't seem that the PC is actually turned on.

Since I'm seeing these lights, I know that the motherboard is getting power. Furthermore, the display VGA port is embedded into the motherboard, so that's not the issue.

I'm just trying to figure out what COULD be the issue aside from a faulty motherboard.

I have a diagram of the D2500HN motherboard which labels everything, and have ensured that the power LED as well as the On/Off cables are plugged into the right spots, although to be sure I've tried flipping these two cables around, and also plugging 1 cable into the other cable's spot & vice-versa.

Is there anything else you folks think I may be missing, or anything else I can do to try to troubleshoot this issue before sending the motherboard back?
