The sound is like a high pitch odd sound that lasts for about 10 seconds and then stops; then starts back up 10 seconds or so later. It doesn't seem to be linked with anything that I am doing either. I sat the log in screen for 6 minute and didn't hear anything until I finally logged into Windows, but it has no effect if I mute or lower the volume inside Windows.
I have a Gigabyte GA-Z77-DS3H motherboard and use the on board audio.
I've been thinking it may be some kind of interference. I redo the wiring in my case today, so is there any chance that the wires all touching like that could cause it? I don't know how it would be hardware though if it doesn't start until I log in.
I also have all the line-in and mic ports muted, so it can't be that.
There is also a very very unnoticeable noise that happens when I move my mouse and can only hear it on max volume with my ear up to the speaker; but I think they may be separate issues; but I wanted to post that just in-case it may be some how related.
I just can't figure out what this might be from, I am desperate for help.
Update: Once again checked log in screen and no sound. This system is a hackintosh as well so I booted into OS X and transferred files for 20 minutes. Heard not even a peep, so it has to be some setting in Windows itself that is causing this feedback.

I actually some how managed to fix this, just hadn't gotten here to update the post.
I didn't mess with any of the wires and it had the same effect on my headset when plugged into the front of my PC case, I was thinking about how it was affected when I actually had Windows start up. So I tinkered around a bunch with the audio settings, combing through everything 20 times and doing trial and error, which didn't seem to work, I don't think. But I figured it was some setting that got activated on start up, so I went through the boot log and turned off/uninstalled somethings and it seemed to have stopped from doing that. I didn't touch any of the wires.
I wish I charted all my attempts to fix it so I could offer advice if anyone else has this issue, but I was exhausted trying different things.
