When turning on my PC I'll get a short buzz just before the POST beep. It only happens when a booting method that allows POST to be initiated. Other than that, my PC seems to be running normal. The buzz does bring a concern, though.

Any ideas?

After finally getting time to move things around and play around with it, it's the electrical pulse to the POST speaker that's causing the buzzing noise. No speaker, no beep or buzzing, I swapped speakers with another PC to test and had the same results. The other PC didn't have any buzzing using the speaker from mine. I have no known issues with the mobo and everything is running normally.

So, if you're also having the issue, try swapping speakers out with someone else if possible. Mine started after a BIOS update so I'm sure it has something to do with that. Most likely nothing to worry about.
