Troubleshooting
Troubleshooting computers is
the
process of getting answers
to
these
five
questions:
•
What
exactly
is
wrong,
or
what
are the
bad
symptoms?
• Where are the
bad
symptoms appearing?
• When do
the
bad symptoms occur?
•
How
bad
is
the problem or
to
what
extent does
it
occur?
•
What
actually caused
the
problem in the first place?
Getting the answers
to
these questions usually makes
the
troubleshoot-
ing process much more effective and less costly. When a failure in a
computer system occurs, remember these questions
and
get
the
answers
to each of them.
After you have all answers possible, decide
what's
the
most probable
cause of
the
problem. Sometimes you'll arrive
at
several choices for a
cause. For each choice, qualify it against
the
answers
to
the
questions
above.
The
most probable cause
is
the one
that
logically justifies
the
correct answers
to
these questions.
