    Lightbulb Sproggy Quick Question

    Ok here are the results of the testing, this should be an easy diagnosis for someone who knows the sproggy.

    --Voltage Std--|--No Load--|---Load----|---Pass/Fail
    ------------------------------------------------------------------
    -----Batt--------|--11.941---|-11.622---|------P
    -----5v----------|--11.707---|-10.405---|------F!!!!!!!
    ----12v--------- |--12.072---|-11.972---|------P
    -----3v----------|---3.303---|--3.2722--|------P
    -(-)12v----------|-(-)11.770-|-(-)11.946|------P
    --(-)5v----------|--(-)5.039-|--(-)5.042-|------P


    *Load is my FV24(im sure its dead) and 12v fan


    I hope that this is just a simple problem. I had it in my system and then hit a MAJOR speed bump and the whole thing crashed. I think that the 12v coming out of the 5v was what fried my mobo and can be fixed. The mobo is most deffinately fried, atleast wont post/beep/or show anything, just turns on the LED and fan.

    Ok, im sure that they are not touching so which chips need to be replaced? Because it is just the 5v that seems to have the problems, which chip is it?

    It would be the MAX787 chip right? because that has the 5v output, would anything else be fried?
