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