    Motherboard is only powering for a short moment then its dead...

    Use diode mode and check. usu here the resistant is low. 40 ohm could be fine. does it start up and run ? does it boot loop ? etc willl be helpful

      40 ohms is fine for PCH, problem is elsewhere. Bulk of the issues I see on main boards is corrosion. The boards are that cheap these days I don't usually bother spending too much time on them.
