In the good old days of cathode ray tubes rolling bands were almost always due to an interference. the AC power's 60 Hz, with harmonics, and the 15 or so kHz horizontal would get harmonically linked to create the bands. They moved because the frequencies were nearly , but not exactly, the same. That's not precisely your problem with modern digital monitors but you did alter the load on the power supply when you installed the new disk. If the supply is now overloaded or is exercising its capacitors a little harder now it's possible that the result could be some rolling interference. Can you turn off the new disk while still having something to look at? Or is it a replacement in a single disk box? -- --> From the U S of A, the only socialist country that refuses to admit it. <-- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
