It is extremely difficult to troubleshoot a problem computer after
it has locked up or shut down. You have to get into the mind of the computer
to find out what it was thinking, what it was feeling. One of my machines
needed to have the hard drive wiped and a new operating system loaded.
The machine was my Web server that was having some software issues that
I did not have the time or patience to try to correct.
The first of the year was a rather busy time for me and so I wasn’t
able to devote my full attention to the task. We had moved our business
to a new location at the end of November and there were some minor issues
that needed to be resolved on a daily basis related to the move. During
the month of December I was focused on installing and configuring a new
accounting system that was to be in place by the first of January. All
of this while trying to keep the business running and taking care of the
normal day to day tasks.
I would spend a few minutes having the machine boot to the CD and get
called away for something that was more important. Two hours later I would
have to start the whole process over because I would come back in the server
room and the machine would be off. Finally this last week I took the machine
off the rack to find out what the problem was. It had gotten to the point
that I could power the machine on and nothing would happen. No boot screen
would show up and no sign of life.
When I removed the cover to the machine and turned it on it was easy
to spot the problem. The fan for the CPU was not turning at all. I turned
the machine off and removed the fan to find a processor that was covered
with a brown film. It seems that one of my attempts to reload the operating
system on the machine had failed and the machine was left running. The
CPU fan had failed somewhere in this process and the grease that is used
to dissipate the heat from the CPU to the heat sink had cooked to a nice
brown color. Heat and CPUs do not mix well so the CPU and the fan had to
be replaced.
After the CPU and fan had been replaced I turned the machine on and
was able to boot to the CD to begin loading the operating system. I finished
the installation and installed the remote access software so that I would
be able to work with the machine from the house. At this point I have a
machine that has the operating system software and remote access software
and nothing else but I am ready to head for the house and get some supper
and continue the process from the easy chair in my living room while I
watch the Spurs game. About eight that evening I try connecting to the
new machine and am unable to so I move on to other things and make a mental
note to look into the problem in the morning.
The next morning after opening up I go to my machine to find out why
I could not connect. I find that it has been powered off. It is still sitting
on the work bench so I figure that it had been turned off by a power outage.
At this point I think that I am finished with my problem with this machine
and I move it back to the server room on the rack so that I can download
and install the updates from there. I get everything plugged in and push
the power button and nothing happens. There is nothing that could have
happened to the machine in the five minutes that it took me to move from
the work bench to the server room so I pull the cover off the machine while
it is on the rack to be sure that something has not popped loose in the
walk. I hit the power button again and still nothing. I reach into the
machine to feel the CPU fan and heat sink to be sure that there is not
a problem with the last item that I was working with. As I press on the
fan the machine comes on. This is not a good sign since this is what the
power button is for so I immediately pull the power plug on the machine
and pull it off the rack to take a closer look at it.
It seems that the power supply was having problems as well and needed
to be replaced. I would assume at this point that the power supply had
been the root of my problem and the CPU fan had been a symptom or result
of that issue. There were no noises coming from either of the fans that
alerted me to the problem. It was a coincidence that the hardware issues
occurred during the same time frame of the software issue that I was experiencing
and the move to the new building. Either way the problem has been resolved,
the software installed and updated and the machine is back in service.
It has been an eventful three months that I would not wish on my worst
enemy but I made it thru and was able to ventilate with you after the fact.
This has been a very therapeutic session but our space is up for this month
so I must go for now.
