    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.

    Just to clarify: when you use the wooden desk, do you use a different power outlet? If yes, try running an extension cord from the metal desk to the outlet by the wooden one.

    Make sure there are no magnets around the monitor. (are there magnets holding things to your metal filing cabinet?)

    if the problem does somehow stem from the metal in the desk top, try putting a rubber mousepad or some other insulator between the computer and the desk.

    Thanks for the replies! I really appreciate

    Chrisprobert: I did try changing outlets, the problem seems to be the metal table... Though I will have to check if I find any magnets in the drawers tomorrow, before trying Merkin's suggestion. Thank you!
    Merkin: I'll try your suggestion tomorrow, and let you know. Thank you!

    Problem resolved with yoga matt

    I followed Merkin's suggestion, and no more flickering!!!
    Seems like the wiring in this old apartment is not grounded, hence the problem with the metal desk.
    Thank you guys so much for the time and advice!

    eMac user, hi I had the same problem too when I moved my eMac to the other side of my room. I realize that it was because there is a electric generator near by. The closer I moved my eMac to the window the more flickers is visible.

    The rubber matt worked, but just at first. I finally had to move the computer and desk away from the wall it was against. Behind the wall is the electric circuit box for the apartment, with a little transformer inside (it's an old building). I never thought there were a circuit box there, also because it's behind a wooden door, which stands 6 feet from the floor.
