I just moved into another apartment, and although I had my emac over the same metal desk in the last two places, now the monitor flickers. I searched for answers, and have tried it all, changing outlets, adding a voltage regulator/power surge protector, and nothing helped, until I moved the computer from the metal desk to a wooden table. I would really like to continue utilizing my old metal desk/file cabinet. Anyone would know what to do to stop the problem? I will appreciate any tips! Thanks.
