Ah, ok, so it's a laptop. While I've had other problems with the integrate Realtek audio, this isn't one I've bumped in to. Creative sound cards on the other hand...
No man, it's making the same noise in both the laptop and desktop, not just one or the other.
I dunno if this was covered, but if you take the laptop outdoors does the noise still occur there? Or at the local library? etc.
I think we've ruled out cable/driver/card problems since the noise is happening in both computers. If not, that would be one hell of a coincidence.
It seems like outside interference is the most likely culprit. Simplest way to start is ruling out whether the interference is in the house, or if it's your entire housing area - thus trying outside or at the library.
If it's in your house, you can systematically turn off (unplug) electronics and appliances around your house to determine what's causing it.
Hey swords, have you looked in your computer for gremlins? Sometimes gremlins like to crawl into computers and smoke crack...

I have an idea.
Do any of your neighbors have a strong CB radio or some other antenna-type thingamajiggy? We had neighbors on the other end of the block that would mess with the TV reception at odd hours each day.
I don't know about the neighborhood rules on the other side of the forest but nobody can stick up their own antennas or anything on this building (which sucks cos I'd like satellite TV - cheaper than cable).
Provided it's something like a stray frequency, can I buy a shielded blanket for the PC or as seedjar said, make a DIY faraday cage to zap that frequency outta the air and keep it from wonking up my soundcard?

Grand Hotel... always the same. People come, people go. Nothing ever happens.
It can be a block or more away. You live near a police station?
