when i touch the device i feel electric shocks on the device,my cell has a steel panel and so does it conduct but the bizzare thing is even my camera which has a plastic casing conducts electric shocks(i just cant believe this).
my usb devices like pendrive and mobile works fine when connected but my camera hangs up when connected to usb port...
yes i built my pc by myself...and ive never removed or added any component since i assembled...
i too felt it might be earth problem but how should i solve it or what should i change...coz at times i do feel shocks on the cabinet of my cpu...
