For the past few months, I've been experiencing an odd random sound on my new computer (as well as 2 other PCs I've tested). It seems to occur only when the internet is connected. I have changed ISPs, bought a new router, and changed service from DSL to cable - but the exact sound continues. I've painstakingly ruled out all hardware or Windows causes.
I've recorded the sound. Here's the link: https://soundcloud.com/finvarra/nuc-sound-2
I realize I'm grasping at straws, but... does anyone recognize this sound - and could it possibly be caused by a ham radio in the neighborhood? Thanks...
