    According to fig. dsc00013.jpg,
    It looks like you connected the 2 diodes (1N4002 - next to the relay) the wrong way. Their cathodes - the side where the stripes are- should be connected together:

    I think he's right....i took a look at my own sproggy and confirmed that. So try that and then tell us if it still doesnt work

    lol, cant believe i did that.

    well after reversing all of the n4007's it will turn on, only if i ground the pin14 lead. is this supposed to happen?

    thank you all for all the help.

    sounds about right - the 2.8 supports the full ATX standard so that you can have a mobo-based power switch. 2.6's still powered on manually.
