Chancer: the DO wire is actually connected to the top part of the mobo. I couldn't use the alternate bottom because the LPC rebuild that was there before took too much from the underside d0 point.
First I'll check to see if the BT wire is touching the metal shielding behind the front panel.
If it is clear and still have problems, I'll do the alternative.
By the way, would this cracked capacitor (top right) have anything to do with the problem
