Possible Faulty Motherboard?

I started a new build a couple days ago and thought everything was going smoothly until I plugged it into the monitor. It looks like all the components are moving and working fine but the monitor keeps giving me the no signal error.

My graphics card's fans are spinning, my hard drive is starting up, my CPU fan is spinning. I checked if my processor was oriented correctly and it was. All the power cables are attached I double checked that the CPU power cord was in the board. My two main concerns are the RAM and the motherboard itself.

The current components I have on the board are as follows
Motherboard - Gigabyte 990FXA-UD3 (4 PCI-E)
RAM - 1x PNY 4GB 1333 DDR3
Processor - AMD Sempron 145
Hard Drive - Western Digital Caviar RE 250GB
PSU - Silverstone 1500W 80Plus Silver (this will be a crypto coin mining rig)
GPU - 1x Diamond Radeon R9 280x

The computer does not have a case as it will be stored in milk crates for optimal cooling for the 2 additional graphics cards I intend to put in it.

This is the machine at the moment.

I believe it might be a faulty motherboard but I am not certain. Any input on how to possibly solve my issue and get an output on my monitor, advice, or further testing would be greatly appreciated.

Other Notes: I have tried every slot with the graphics card and the ram and nothing different occurs.
I have no CD drive I will boot windows 7 off a USB.

Its hard to tell on the pic did you plug in the PCI-e power into the GPU? It looks like you did but just making sure. Plug the monitor on the onboard graphics. Look in bios and set the primary display adapter to PCI-e, save and exit then plug monitor back in PCI-e card.

Ok not all board have an onboard VGA and the PCI-e power is in. There are a few tests to prove which component is at fault. First (you may have already done this) if you have a multi port monitor make sure the relevant input is selected via the monitor functions or mode button (on the monitor). If thats correct you need to prove the display cable is working, if possible use another cable to test. If still no joy the next step is to try the GPU in another machine, with luck you will have a friend of family members computer to try this. If the card works then its a board fault, if not its a faulty card.

Sorry there are a lot of tests but with fault finding there is never a quick way.
