Worth trying a simple fix
I've had a similar experience but one where I actually got a BSOD after reaching for the power button to turn off my PC. For a while I thought it was related to me closing certain applications down and nothing more than coincidental timing with me then reaching for the power button, but eventually twigged that it was static related.
As a simple experiment I ran some stranded copper wire from the seatpad down to the floor, with each end fanned out into a rudimentary brush shape, after which the problem didn't reoccur, despite the floor being essentially insulated with carpet.
I'd say it's worth a go if it's causing you a problem.
