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

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.
First run through the items in the preliminary checklist above.
