Please help me. My computer craves for my death. It eloctrocutes me regulary. I get eloctrocuted in the following cirrcumstances: When I touch the metal parts of the case. When I touch open ends of cables connected to the comp, as the speaker cable or the USB to the camera. And last but not least, I was shocked while playing my electric bass, when the amplifier was leaning against the comp! electricity flowed from the strings to my fingers!!! That was spooky. Anyway right now I'm afraid to touch it. And I'm not connecting my precious digital camera to the computer until I solve this prob. Do you think that I should replace the Power Supply, or perhaps there is something else I should check, or should I just call a pro? Thanks for your time, cool-RR.
