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. Try loading
another copy of the software.
If an error message appears while you are 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 OS documentation.
If you cannot find a software problem, check your
hardware. First run through the items in the preliminary
checklist above. If you still cannot correct the problem, try

for individual components and peripherals.
