Have you looked inside the PS? What you think of a separate cables may
be joined at the base in the PS. And then if one cable has a high
resistance short, it affects voltage on both legs. And if the output tap
feeding those two wires (even separate wires on the same "bus" or "tap"
are "joined at the base" electrically speaking) has a problem ... it
appears on both wires.

That said, *usually* problems in the wires are "opens" and you just lose
that one "leg".

It *might* be cheaper to insert a PCI controller card than replace the
mb.

And whisper sweet nothings into its little electronic ears. :-)
