So I just built my gaming PC. Not that fancy after all. I put it on my wooden desk. And i plugged it into my stavol for 220V. My monitor also plugged into the stavol for the same volt. On my desk there's 1m mouspad with metal build mechanical gaming keyboard and the mouse and also there's my laptop. My laptop, keyboard and mouse sometimes instantly zap me when I touch the metal part. I'm planning to put a nail into the wall and wired it with copper will it work as grounding?
