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 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 operating
system documentation.
Hardware If you cannot find a software problem, check your
hardware.
