I have noticed this behavior ever since I'm using my old pc.
my old pc and new one is located at the same place.
(As I just replaced it).
I've noticed this weird behavior when someone turns on the lights.
I'm having alarm sound that a device is unplugged, and when I turn off the light.
the same alarm sounds.
the lamp is a flourescent lamp and it is beside the PC tower and the only thing that separates them is 2in. wooden wall. if you need a photo. I'll upload it for you.
is it the static discharge of the lamp that causes this?.
