Adding extra grounding cable to computer

Update: Improved grounding with one grounding cable at top side panel and one at bottom side panel straight down
to the desk's metal leg hold by a metal clamp. The ground to the wall socket of computers are not remove. And the faster route to earth is having ground cable straight to the ground with the help of earth gravity pull. Any up slope of the ground cable will cause high resistance grounding and active grounding box can correct it. The purpose of this grounding is to remove high amount of electric static charges cause mainly by environment's electric field as shown below. I actually able to measure at about 800 v/m of electric field. Opinions ?
