The problems may be caused by your software or disk. If you
cannot load a software package, the media may be damaged
or the program might be corrupted. In these instances try
loading another copy of the software if possible.
If an error message appears while you are using a software
package you should refer to the documentation supplied with
it as this will usually include a problem-solving section or a
summary of error messages.
Next, you should check any error messages against the
operating system documentation.
If you cannot find a software problem, you should then check
the setup and configuration of your hardware. First, run
through the items in the preliminary checklist as described
previously. Then, if you still cannot correct the problem, try to
identify the source - the next section provides checklists for
individual components and peripherals.
