Win 7 PC wakes up when a lamp is turned on or off

[liquidmetalrob]

For some reason my computer wakes up from sleep mode when I turn a lamp on or off in the same room, it's not even connected to the PC except through the power lines I guess. I also get the same thing when unplugging the speakers from the wall. I investigated by running "powercfg -lastwake" and that told me it had been woken up by USB, the same thing I got when pressing keys on the USB keyboard. So I'm baffled. Can anyone help at all?

Did you check your PSU?
Since it gets affected by changes in the power grid I would suggest focusing on PSU and the plug its connected to
Easiest way to test it is to change its location and see if it will act same way

OK, thanks. I'll try plugging it into a different socket/outlet.
