I figured I would share this, Uniserver found the bad connection, and I looked at the couple CC boards I have here and one of them had the exact same issue. 

Ill take pictures of the actual issue, and the fix a little bit later. 

But attached is a picture that Uniserver has drawn up. 

Basically, one of the traces to the CUDA chip crystal oscillator rots out, and breaks the crystal connection to one of the load capacitors on the bottom of the board, and sometimes the CUDA chip itself. 

So, if the CUDA chip doesnt have a clock pulse, Well, its not going to power on or keep time/ADB. 

In the diagram, youll see a dashed yellow line. Thats the trace that breaks. Well, one of them.
