Don't take me as being compulsive, but I have a concerning question. Yesterday, my computer was turned off and unplugged from its wall outlet, and I went to move it and upon touching the case (metal), I received a static zap. It powered on alright, and when plugged in to the three slot wall outlet, no static zaps occurred upon touching it. Could the static zap from metal case before plugging it in have caused any internal damage?
