[gui-talk] Computer related questions...

[Cindy Handel]

Thanks Steve.

Well, a year or year and a half ago, we were having electrical problems; 
which caused us to have some work done, including new wiring in this outlet. 
But, now we have no other problems in the rest of the house.  Light bulbs 
don't burn out often, and no one has mentioned them brightening.

The only time the power supply makes noise is when the computer is first 
turned on.  The fan is currently running.  But, I believe, if I leave it go 
without getting it repaired, for awhile, the next thing I'll notice is the 
fan will stop running, or run sporadically.

I will take the surge protector with me, when I get the computer fixed.

Cindy,

These are very annoying problems.  The power supplies in computers are a 
good bit more complicated than even
those in a monitor.  Therefore, it can happen that a poor electrical supply 
can affect a computer but not other devices.
There are times when low voltage can dammage a power supply in addition to a 
surge.  One thing that I might be
suspicious of is your surge protector.  Perhaps something is going out 
there.  Also, is there a pattern to when you hear
the buzzing?  For example, can you associate it with a particular time of 
day?  Have you ever noticed if it coincides
with your refrigerator running?  Because of how electrical wiring works in a 
building, a heavy load placed on your
electrical system such as when a refrigerator is running can cause the 
voltage on other outlets to change.  It can even
cause the voltage to be raised in some cases.  Have people ecver commented 
on your lights brightening or dimming?
Do you have any problems with light bulbs seeming to burn out too soon?  If 
the answer to all these questions is "no,"
then it seems likely your general power is all right and that you might be 
suspicious of your surge protector.  You might
bring that into the store with you and see if they can test that out as 
well.  I have purchased computers from stores
that build them and I like that approach.  It really does not seem likely 
that this problem is something they are doing
wrong, unless they are using power supplies that are not protected well. 
You might ask them if they have other brands
of power supplies this time, and make sure not to use a reconditioned supply 
to save money.  Sometimes these are
offered to save money, and while they can be worth it, given your 
experience, I think I'd stay away from them and see
if that makes any difference.

Good luck.

Best regards,

Steve Jacobson
