Re: [PLUG] Mysterious system freeze
|
- Lessons learned -
Well, thanks to those who replied to this email... I really had a tough
time with this until last week. The "freezes" were so random and so
rare (about once a week at the _most_) that I was at a loss to pinpoint
a single cause.
Then, last week I went away for 2 days and left the computer off. When
I returned and powered it up there was a green LED but no activity... no
video, no whirring of disks... zilch.
Dissassembly revealed a foul oder from the power supply which leads me
to believe that it was "going - going - GONE!". I replaced it on Friday
the 11th of July and so far (knock on wood) there is no sign of the
"freezes".
Had this not happened, I was preparing (if the problem did not cease) to
replace the memory and the power supply as a SWAG* solution.
Thanks again.

Today, wanting someone else's money is called "need", wanting to keep
your own money is called "greed", and "compassion" is when politicians
arrange the transfer.
