No signal from Monitor, everything else works. Please help >.

Hi, I have recently decided to go into the Ethereum mining world and I purchased the parts to build a new mining rig.

After a friend helped me put the rig together and I got all the remaining cords I attempted to fire it up and was delighted to see the everything turn on except for the monitor which reported "No signal". I thought maybe the monitor was broke so I tried a second monitor same thing, I then tried different cords to no avail. At this point I have no idea what could be wrong except maybe trying the PCin cord and am desperately looking for any advice/help.

My build is: x ASRock FM2A88X PRO3+ Socket FM2+ 95W / FM2 100W AMD A88X (Bolton D4) SATA 6Gb/s USB 3.0 ATX AMD Motherboard
