Have you checked for 5V, 12V and ground on all the CPU socket pins as detailed in the build manual?

So there's no 12V supply into your MS at all?

You either have a diode in backwards or a faulty part pulling your 5V line to ground. Check all the components you just listed which should have voltage but don't for orientation, then remove them until the 5V line comes up. Obviously removing U5 will stop the 5V line coming up.

Okay i went and to my best of knowledge im thinking d10 is bad. When i try and get a voltage reading from D10 i only see 12v on one side. The side i see no voltage on is the banded side.

Sounds reasonable enough. Try swapping it out

One of the above. Go and google for how to test the few components that could be at fault, then do that.
