Custom PC | No Display

[ThreatZone]

I have just finished building my custom PC from the list below and when i boot, the fans runs but it does not detect the anything on screen. The screen will say there is no input detected and go to sleep. I have tried using the HDMI and VGA cable and none of them show any difference in result. I have even tried it on another screen. Anyone have any idea on what maybe wrong? The list below is my rig.

The attached Image is my setup

I know the cable management is bad but the case is small.

Does your computer post? This is shown by either a beep code or a number code shown on the motherboard. If it does, refer to your motherboard's manual for finding out what the post code means and it'll tell you what's wrong.

 

If it doesn't work:

Try removing the GPU and trying to power on again.

Test your RAM, each stick in every slot individually.

Make sure you're plugging the monitor into the GPU, not the motherboard.
