So i always put my psu in my case and switch it off for grounding. But this time i noticed something weird. I tried to screw my motherboard in before this and I noticed a tingling sensation everytime i screwed a screw in or pluggeed in a connector. Did i just exert all the static in the world on the parts or does this tingly feeling mean something else. It seems to happen when i touch the io sheild and screws to the power supply as well.
