hey, i have a pc and it is running on a desk. on one side is one pc (alienware aurora 7500) and on the other side of the desk is my old p4 1.7ghz. now i try to get the pc (p4) going but when i plug in the power supply cable, i get a current flowing through my case. i dont know if this is bad or if it can damage the components or what. the current is not strong enough to hurt me but it is annoying coz whenever i touch the case i get the current going through me. has anyone got any ideas as to why its doing this? cheers
