Before using a peripheral device or application software that is not an
authorized Toshiba part or product, make sure the device or software can
be used with your computer. Use of incompatible devices may cause injury
or may damage your computer.
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

The problems may be caused by your software or disc. 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.
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.
