With my new carpet and habit of wearing slippers I've had a lot of trouble with ESD. Big painful zaps that would reboot my keyboard and sometimes cause other mischief. I was worried about causing permanent damage. I got in the habit of touching the grounding screw on the wall outlet while sitting down which basically fixed it.

Strangely, if the computer is asleep it will wake up when I zap the ground screw. I'm still wondering how that happens. I guess it gets picked up by the wires which run to the power button? My PC case is pretty awful at EMI shielding like most modern custom PC cases.
