Since i got a new keyboard (Hyperx alloy fps) which has a metal frame instead of a plastic frame like my old keyboard, i have gotten random jolts of electricity. Not super painful, just a bit of discomfort and getting the reaction to pull away my hand. I thought that the keyboard was broken, but i noticed, that it only happens when i touch my wall radiator (which is connected to ground). I get the same jolts, if i touch anyting metal on my case, and the radiator at the same time. I got the brilliant idea of connecting a alligator clip wire, one end to my psu grill, the other to the radiator. When i put the alligator clip to abou 2 mm from the radiator, i see a red-ish electrical spark. I measured the voltage of that cable, and i got a result fluctuating from 1.1 to 1.0 Volts AC. No, my pc is not in a grounded inlet, and i dont have access to one in my room. How to fix?
