To identify and isolate an anomaly with your computer, follow these
steps.
1. Shut down the computer's operating system by 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. Connect power to the computer.
When you apply power, check the power on self test (POST).
One of three events will occur.
• The computer completes the startup process.
• An error message displays to indicate a nonfatal fault. You
may have to acknowledge the message before the startup
process continues.
• The startup process terminates if a fatal error occurs.
7. If the system starts, isolate the anomaly by connecting peripheral
devices one at a time until the anomaly occurs.
If the anomaly is with a specific software package, or driver,
reinstall the software.
