    Thats a Quanta QL8 / TW8 motherboard.
    And this is the discrete GPU version of yours, might help.
    And if you can share the symptoms I can help u. I repaired lots of that motherboard when I was working on a RMA center.
    Most problem is shorted mosfet,tantalum caps and cold solder at Vcore chip.

        What do you mean LDO is 0 ohm ? is it totally shorted ? also check the +3VPCU rail to the ground.
