Try disconnecting the USB connection to the PC and see if the problem recurs.  I use the 1500VA APC ones in the lab at work.

@mhrackin: Is it powered by a UPS?  I've had some issues with the UPS monitoring SW doing things like this.

It is indeed -- I have a honking big one (although I don't like to boast :-)

@mhrackin: I recall some recent postings on "Tales from the Cube" (on a sister site) that identified this as root cause of a number of strange occurrences.

Hmmm -- the main tower in my office keeps on locking up for no apparent reason -- we've scanned it for malware and viruses --- we've run burn-in software to stress the machine and wee've also run deep memory tests overnight -- nothing shows up. I wonder...

@max: "that was the very first thing I checked"

So what else did you check?  How about your "home away from home" office?  I don't know how recent the building is, but even in very new commercial space, I've found poor grounding practices that can result in significant ground differences between separate branch circuits even in the same room! I recall some recent postings on "Tales from the Cube" (on a sister site) that identified this as root cause of a number of strange occurrences.

@mhrackin: On a possibly related subject: what disappeared from the "most commented" list that allowed the hoary old blog about appliances muttering behind our backs to reappear at the bottom of the list?

Why, it's strange you should ask, but by some strange quirk of fate it was this very column.
