I got a shock while hooking up my cable tv to my computer and I tested it for voltage and I got 112.8VAC wall voltage is 118.2 (My House normal)I know this is not normal so how could the voltage get there? and when I connected the computer to the outlet I was greeted with A spark and a tripped breaker (Computer is grounded 3 pin plug rest of my home enterainment stuff is not)
