        To all of the users that are having problems with the noise
that is generated by your monitors, here is a little information
about a similar problem that I had.  I used to have that monitor
"squeal", and to alleviate the problem when it got REAL bad, I would
turn the monitor off for a few minutes, then turn it back on.
Usually the noise would be a little quieter, and/or it would be a
different pitch.  About a month ago I asked for help about my system
hanging at random times, after running for random periods of time.
One of the suggestions was that the ADB Bus may be fried, the other
was that the power supply was going out. My cheapest solution was to
purchase a new power supply, which I did (AE's Heavy Duty Power Supply).
Anyway, after reading the multiple number of posts about the monitor
noise, I would like to inform you that my "noise" has now quit, ever
since I installed the new power supply.  My suggestion would be to check
the connection of the power supply to motherboard, or check out the
power supply itself.  Does anyone who is having the noise problem have
one of the older Apple Power Supplies?  I would like to see if there may
be a correlation between the age/type of the supply to the problems of
noise.  Also, does anyone still have the information laying around about
Apple's offer to replace the "defective" older power supplies with a new
one?  Does anyone think that I could possibly get Apple to reimburse me
for my old one?  And to those that are looking into a new power supply,
I would highly recommend AE's power supply, it is nice, especially for
those that have highly used systems with lots of accessories.
