Troubleshooting Your System 131
Troubleshooting External Connections
Loose or improperly connected cables are the most likely source of problems
for the system, monitor, and other peripherals (such as a printer, keyboard,
mouse, or other external device). Ensure that all external cables are securely
attached to the external connectors on your system. See "Front-Panel
Features and Indicators" on page 13 and "Back-Panel Features and Indicators"
on page 17 for the front- and back-panel connectors on your system.
Troubleshooting the Video Subsystem
Problem
• Monitor is not working properly.
• Video memory is faulty.
Action
1
Check the system and power connections to the monitor.
2
Determine whether the system has an expansion card with a video output
connector.
In this system configuration, the monitor cable should normally be
connected to the connector on the expansion card,
not
to the system’s
integrated video connector.
