      so which is this mobo, the one you paid for waiting for the RMA to come back, or the RMA’d mobo?

      there may be no sparks now cause the ‘damage’ is already done.
      I would think there is a integrated chip on the mobo somewhere that controls that USB header, and it is now fried.

      why the mobo never started by shorting out the PWR SW pins is one mystery, and why it does start shorting out those USB pins is another.

      sorry - no logical answer for that! (apart from a faulty mobo)

        Its the RMA mobo. Yeah, ive buildt 100s of systems but never experienced this issue. But as long as it works its fine. Just trying to think of something else other than a screw in that front usb. I tested wit 2 power button cables, its turning on, but not enough power to start it. Im no electrician, and this issue i cant find anywhere online. Somethings have to be the first right

          whoa - hang on, I must have missed that little gem.

          so shorting out those USB header pins just makes the PC ‘come alive’.
          you still can’t get it to stay on and get into Windows???

                  hey, the screw works, so why go for another solution - keep it simple.
                  let’s face it, that mobo has issues, the startup method could be the tip of the iceberg.

                  personally, I’d RMA it or at least not use it - having a hunk of metal knowingly shorting out pins to get it going just seems wrong.
