    Probably the capacitors have gone. Especially if they have just been sitting doing nothing for years. MoBos suffer the same, look at the big electrolytics to see if they are bulging.

    Andrei - it looks as though you have a rubbish supply from the pole. You already have an earth fault, maybe you have a poor supply due to a corroded connection.

    Clive - is it not possible to put some big caps on the output of the SMPS's. Don't they have quite a wide input voltage range anyway ?
