Smoke from motherboard, help!

    Just put in a PC Chips P25G motherboard to replace the failed one in a
    client's EMachines 2542, Celeron 2.5ghz cpu. Hooked everything up and
    plugged in power cord into the power supply. Smoke immediately began
    emanating from the the ITE I/O chip
    (http://www.ite.com.tw/product_info/PC/Brief-IT8705_2.asp). At this point
    the computer was not turned on, just plugged in. I unplugged the power
    cord, and then unplugged all devices and from the mobo except the two power
    supply plugs - the ATX and 12v plugs. I plugged the power cord back in the
    power supply, and same thing happened. Then I connected a different power
    supply - one I know to be working fine - and the same thing happened again,
    although this time it took longer for the smoke to appear. Neverthless, the
    chip got white hot.

    Is this simply a defective mobo, or is there possibly something else at work
    here?

    thanks,

    You aren't supposed to let the smoke out!

    It'll stop smoking eventually...

    Seriously, ditch that board and test any other component attached to it
    separately before attaching to another board.
