Thank you all for the replies.
This has gone from the standard weird to the “Holy shit, that’s freaky deaky” weird.
So, I begrudgingly accepted that something is awry with my computer, until my meeting with my thesis supervisor today. His computer has the monitor off, but the speakers on so he can respond to outlook.
I cut him off mid sentence to ask him what the hell was that. He responded that it was some sort of notification or something, then paused and realized he had no idea. Could it be, in fact, the windows search dog? I have been searching a lot of files lately…but I always close the explorer windows when I’m done…
It’s not my blackberry. The blackberry interference is a different sound, more akin to incoherent computerized morse code; I hear that one periodically on my computer…and my TV…and my digital piano…and my car stereo…etc. etc.
It always comes in twos. And it’s very metrical and even. But now I need to find out where that dog is hiding and see if he’s the culprit.
