Troubleshooting
Hardware and system checklist
This section discusses problems caused by your computer’s hardware or
attached peripherals. Basic problems may occur in the following areas:
System start-up
When the computer does not start properly, check the following items:
Self Test
Power Sources
Power-on Password
Software
The problems may be caused by your software or
diskette. If you cannot load a software package, the
media (usually a diskette) 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.
Hardware
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 to identify the source. The next section provides
checklists for individual components and peripherals.
