[G4] Bad Power Supply?

You may be experiencing brown out conditions with your power company.  If
you have an APC or other uninterruptable power supply, put it between the
source and your machine.  "Brown Out" conditions will be signalled by the
APC sounding that it is activated....  Wouldn't be without one.

It shut off 3 times in one day. I moved the plug and blew out the dust.
After that, it worked fine for a few days. Then, it shut off again
yesterday. I turned it back on last night, and it has been running
since then with out a problem.

It has been plugged in to the same outlet for almost a year with out
this happening.  I'm going to replace the cord and see what happens.
