In this sample, replace the Win32_OperatingSystem and Name in the code to the ones you are interested in (i.e. Win32_BaseBoard and SerialNumber for motherboard serial).

As @Mitch mentioned, you can use the WMI Win32_BaseBoard class, SerialNumber property. Alternatively, for processor ID you can use the Win32_Processor class, ProcessorId property.

    Worth noting that on multiple processor machine Win32_Processor can return different results depending on the processor that is running – Elemental Jul 23 '10 at 09:25
