Last month we discussed
some of the hardware problems that can occur with your system and affect
the software that you are trying to use. Some of these problems can manifest
themselves as what we believe are software problems. There are a number
of different ways that your computer will tell you that something is wrong.
Some of them will be fairly obvious and easy to figure out. Remember the
five-dollar CPU fan? The fan was the root of all the problems that the
customer was having. Remember the key word "root". Others can hide from
you and it could be weeks or even months before you are able to pin them
down. Let's take a look at some of the other problems that can effect your
system.
If you are getting an error message, or your system is locking up while
booting, you need to ask yourself what has changed. Have you installed
any new programs or updates to the programs that were already on your system?
Did the errors start to appear after you installed that new modem or sound
card? When did the errors start to occur and what is different about your
system now from before the errors started to appear? Can you reproduce
the error on a regular basis or is it an intermittent problem? If you can
pinpoint the beginning of the problem, try to step backwards and see if
the problem goes away. If the error started when you installed that great
new game, uninstall the game and see if the problem goes away. If the new
sound card is creating the problem then take it out of the system to see
if the problem goes away. In both cases, if the problem goes away then
it is time for you to do some research.
You can either call up the manufacturer of the software or sound card
and spend the time to get the whole story explained to them, or you can
do a little investigation on the web to try to find the answer for yourself.
Or you can go one step further, call them up and search the web at the
same time. Either way you will end up on the web if the problem can be
corrected with an updated driver or a patch to the program. I will usually
go to the web first to check for updated drivers and patches before I will
spend time waiting on hold.
If you choose to try to correct the problem yourself, let’s be sure
that you understand a few simple principles that are involved with fixing
your computer. There are some times that a different error message can
be construed as making progress. Usually I like to try to have fewer error
messages and not just different ones. Be sure that as you attempt to fix
a problem that you have, you are careful not to make the problem worse.
This can be in reference to hardware as well as software.
When you are trying to sort out a hardware problem, the first thing
you need to worry about is the static electricity that you create by moving
around the house. This static electricity, when discharged, is called ESD
(ElectroStatic
Discharge). It
can damage or destroy a card and then you will be chasing your tail for
a lot longer. If you decide to open your computer for anything other than
to blow some air in to clean it out, I would suggest that you take it to
the kitchen or some other room that does not have carpet. Carpet will create
more static electricity than any well-grounded tile floor. Let’s stay away
from the sink though. That is a whole other ball game there.
The next thing is to plug the computer into the wall. This will insure
a good ground for the system. Before you touch any of the components inside
the computer, put on your grounded wrist strap. These are available at
most electronics supply stores. Now you need to touch the metal case to
dissipate any charge from your body. Better to shock yourself on the side
of the case than on one of your cards.
ESD is probably the leading cause of computer component failure. The
Electrostatic Discharge Association has an extensive series of articles
on the subject. The web address is http://www.esda.org.
According to the article, it is estimated that as much as 33% of electronic
parts are lost to ESD on an annual basis. This would amount to billions
of dollars lost in product as well as time spent tracking and fixing the
problems.
The tiniest spark from the end of your finger is caused by 1000volts.
The larger car door and door knob sparks can be as much as 10,000 volts.
This is thousands of times what it would take to damage an electronic part.
You can ruin a circuit board or diode on a modem or other card and not
even feel the spark. You could ruin a part and the failure won’t show up
for years to come. The best defense for ESD is to use proper handling techniques.
-
Stay away from the carpet
-
Keep the computer plugged in
-
Wear a grounded wrist strap.
There are many more devices and tools to dissipate static electricity but
these should be enough for the jobs that we attempt.
There are a number of ways that you can protect yourself when trying
to sort out a software problem. The first rule to remember is that you
always want to be able to get back to where you came from. You don’t want
to make the problem worse and then not be able to undo what you just did.
With most of your software programs you have an undo button to press if
you make a mistake. When you are working with system files and making changes
you will not have that luxury. The most important thing to remember is
to always work with a copy of the original file. This makes it easy to
get back to square one. All you need to do if you have totally messed up
you system.ini is to copy the original from wherever you have saved it,
back into the Windows directory. When I am editing files on a customer’s
computer, I will simply make a copy of the file in the Windows directory
and use my initials as the extension. This way I know that I can get back
to where I began without any extra headaches. If you do not want to go
through the trouble of the DOS prompt then you can still make a copy within
Windows Explorer. If you right click on a file and then left click on copy,
this puts a copy of the file on the Windows clipboard. If you right click
within the same folder and then left click on paste, then you will have
made a copy of the original file within the same folder.
A great tool that Microsoft has come up with is called the System Configuration
Utility. For those of you with Windows 98, you can access it by clicking
on the Start button, then Run, and typing msconfig into the Open box and
pressing OK. This program will allow you to create a clean environment
for troubleshooting your system. Listed within the program is a copy of
the autoexec.bat, config.sys, win.ini, system.ini, Windows Startup folder,
and some of the files that are loaded from the registry. For those of you
with Windows 95, the program will run on your system but is not part of
your version of Windows. I have used it a number of times on systems with
all versions of Windows 95 and have had no trouble at all.
If you are having an error message as your computer goes into Windows,
you would use this tool to disable some of the items that load as your
computer is booting up. By the process of trial and error you should be
able to find out what startup program is causing the problem and either
eliminate it or update with a more current version from the vendor.
The best way to use this tool is to first choose the Selective startup
and take the check marks out of all the files below it. This will create
a very clean startup for your computer. If the error does not appear after
this then you would go back into the configuration utility and add one
of the check marks back to the list. Continue with the process until you
find where the error is occurring. After you have located which area of
the system files that is causing the problem, you then need to go into
the specific file by choosing the appropriate tab within the utility. At
this point, you will be choosing between all of the files within one of
the system files. Use the same trial and error process to identify which
of the programs is causing the problem.
When you find out which of the files is causing the error you will be
closer to finding a solution to the problem. If you find that the file
that is loading your scanner software is conflicting with your printer
software, then you have two places to start to look for a solution. I personally
would start at the scanner manufacturer page. Check to see that you have
the latest version of the scanner software. Look at the CD or floppy that
you used to install the software. Open the program if you can and click
on Help in the toolbar and then About. If you cannot find the version number
there, go into the folder that the software is installed in. Look for a
readme file that might give you the version number. After you have found
what version of the software you are using, you can compare this to the
latest version that the company has available for download on there website.
Another useful tool that most of the companies have available is what
is called a Knowledge Base. This is a database of all the problems that
other people have had and the procedure that was taken to correct them.
This is what is called experience. There has only been one time that I
have been the first one to have a particular problem that the tech support
could not correct. Most of the problems that we encounter are problems
that someone else has already had. You need to do your homework when you
have a problem. Do a little digging on some of the basic things that the
tech support is going to ask first thing. Try to find the error that you
are experiencing in the knowledge base. It could save you a lot of time
and heartache and it could be a lot simpler fix that you would have ever
imagined.
When trying to correct a problem that you have with your computer, be
sure that you have a plan. Be sure that you are not making things worse.
Be sure that you can get back to where you originally were before you started
to fix it. Always work with a copy, not the original and always protect
against ESD whenever you are working inside your computer.
