Ever since I've gotten my 512 Mac repaired, I've noticed that the screen has a tendancy to expand and shrink when either of the two drives are running. Anyone have any ideas why this is happening? Pertinent Poop: -512K Mac, two drives -Fan is placed on top to keep it cool. -Surge Supressor is used. -Ground for Mac is homemade, i.e. to cold water pipe (but has been tested by voltmeter to be true ground). Any help would be greatly appreciated. Thanks in advance...

It sounds like either 1) your supply has some substandard parts on it, or 2) your are running too many things off the same circuit in your house (or where ever you have your Mac). I would be on the first rather than the second, this may also be an in- dication that your PS is on the way south... David
