Is there a way to run a diagnostic check for this motherboard? I tested every other part in my sons rig in another rig and all are working fine. It's the craziest thing.... it seems sometimes he plugs his headphone in the front panel jack and his keyboard stops working.  I tried to re-create it and I can't. So now and then it happens.  He has an EVGA x299 micro mb, an EVGA 2080 Ti FTW3 gpu, EVGA 1000G2 ps, 32gb G.SKILLF4-3200C16D32GVR ram(16-18-18-38 1.35v). I have it on my dining room table with an EVGA GTX 970 and I can not re-create the problem. I have given him the rig back and it works for a short time (maybe a week) and it happens again. I am lost.  Thanks for any ideas.

    I'd be suspect of the - Case's front panel jack
     
    Is it possible to plug head phones into MB directly ... might need an extension

    Ideas, or, really, questions:

    1: Is the keyboard in a front panel USB connection? If so: try a back connection, see if it still happens. If it doesn't, check all front panel connections to the motherboard, including all sets of USB headers.
     
    Basically, I'm wondering about grounding issues on the case's front panel, particularly since it happens in response to a physical action - plugging in the headset. The Obsidian 350D's front panel looks pretty accessible, you might check for cable and/or connector issues. I kind of suspect you're either putting signal (or impedance or just anything, leaking from the headset) onto the USB's ground line. Or something.

    2: When the keyboard quits, does it stay quit, or is it momentary or for only a few minutes? What makes it start working again? Does unplugging it and plugging it back in (and hence creating a new USB device connect) make it work again right away? Or do you have to power cycle?

    3: Just to sanity check: the audio block is HD Audio and not '97, right?

    I thought about the front panel, I'll look into that today.

    I am going to check the front panel today, maybe one of the cables from the front panel is shorting against a metal part, who knows.
