Co., Inc., Everett, WA Lines: 27 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...
