Dude, you really need to make sure your gear is grounded properly. You should not be getting electrical shocks from touching stuff. I can't begin to tell you

Dude, you really need to make sure your gear is grounded properly. You should not be getting electrical shocks from touching stuff. I can't begin to tell you how many times we've had screwball problems with equipment that had floating voltages due to poor earthing---problems that went away the minute we fixed the wiring. (The guys maintaining said equipment though nothing wrong of the fact that they were getting shocked and said nothing about it for months!)
