the media may be damaged or the program might
be corrupted. Try loading another copy of the
software.

using a software package, check the software
documentation. These documents usually include
a problem solving section or a summary of error
messages.
Next, check any error messages in the operating
system documentation.
Hardware If you cannot nd a software problem, check your
hardware.
First run through the items in the preliminary
checklist above. If you still cannot correct
the problem, try to identify the source. The
