Chapter 5 System Troubleshooting
Troubleshooting Procedure Follow this procedure to identify and isolate a problem.
1. Shut down the computer’s operating system using the
appropriate method for your operating system.
2. Disconnect the power to the computer.
3. Disconnect peripheral devices such as a printer or external
drive.
4. Connect the keyboard and mouse, if used.
5. Check the video connections if using an external monitor.
6. If the system normally boots from the hard drive, make sure a
disk is not in the floppy drive.
7. Connect power to the computer.
On powerup, monitor the Power On Self Test (POST). One of
three events will occur.
•
The computer completes the bootup process.
•
An error message displays to indicate a non-fatal fault. You
may have to acknowledge the message before the startup
process continues.
•
The bootup process terminates if a fatal error occurs.
8. If the system boots up, isolate the problem by connecting
peripheral devices one at a time until the problem occurs.
If the problem is with a specific software package, or driver,
reinstall the software.
9. If the problem is not related specifically to a software installation
or peripheral device, refer to the troubleshooting checklists.
