On the metal hinges for my side panels I can feel a constant flow of electricity. The hinges are made out of metal and are on the backside of my case. I tried taking the PSU out of the case and tried running the system that way. This eliminated the feeling of electricity. The PSU itself didn't give me any shocks when I touched it. I tried changing the PSU, but the issue was still there. My house is grounded. Can anyone help me?
