Ouch!  I hate motherboard faults - they are often hard to pin down. At
least you seem to be getting somewhere now with diagnosing this one.
If it is a mobo problem, then it will likely only affect one or a pair
of SATA ports, so the mobo may well be usable still if you add a PCIe
SATA card to replace the bad ports (presuming you have room to do
that).  It pays to put some tape over known bad ports, so you do not
accidentally use them again.
