once i noticed that there was a potential difference of about 4 Volts between the neutral and ground of the socket in which i plug in the power cable of my computer. i checked the computer chassis with a tester screwdriver. the bulb of the tester lit up. somone suggested that u should ground the chassis yourself cause this may hurt the internal of the CPU. he told me to take a piece of metal, loop some wire on it, bury it in your garden and then take the wire to the chassis of the CPU. i did that. and u know what? when i checked the chassis with my tester the bulb did not lit.
now the bad ground is still there and the ground i made is also there (connected to the chassis). my question is that is it safe to keep both grounds connected to the system. which one should i take off.
and i havent noticed anything unusual happening. all of it works fine. no ground loops. no 50 Hz humming. before the CPU there is a stabilizer. sometimes its in boost mode and sometimes its in buck mode. nothing unusual there too. but still im quite concerned about it.
