Adding extra grounding cable to computer

Update: Improved my external grounding to for my playstation computer. Used specially made 14AWG multi strand grounding cable and bigger cable lugs. One end is bolted to the top/bottom of the side panel and the other end
clamp to the bottom of the desk metal frame by a metal clamp touching the floor. For a start visual/audio
are more gently than the improvement. To my knowledge, peoples who exposed to fierce visual/audio can easily
get angry, mad, or eve resort to violence.
