Your problem is very likely a wiring problem. You have a bad contact somewhere. It looks like you have soldered individual pins on the motherboard (not sure)? I really recommend to solder instead dual rows pin headers (2 x 5 pins, 2.54mm).

Dupont connectors are also often the cause of problems, especially if you have built the cable yourself.
