I'd probably report the fault immediately to whomever you bought the
motherboard to get a warranty replacement. Otherwise, you might get
stuck having to buy a replacement (http://snipurl.com/6c8l) at a cost of
$17 plus shipping.
However, before sending it in, just go ahead and check for a short
yourself. Use a multimeter, ohmmeter, or continuity tester to check for
a short. It is possible the signal ground is supposed to be shorted.
The backplates and the connections there would be a point of entry for
ESD and EMI so the short from signal ground to chassis ground might
limit the impact of ESD/EMI entry onto the signal ground wire and thwart
it getting inside. Rather than wonder about a short, just check it.
