Troubleshooting Your System

Troubleshooting System Startup Failure

If your system halts during startup prior to video imaging, especially after

installing an operating system or reconfiguring your system’s hardware,

check for the following conditions. See "System Memory" on page 63.
For all other startup issues, note the LED panel indicators and any system

messages that appear onscreen. See "Power and System Board Indicator

Codes" on page 21 for more information.

Troubleshooting External Connections

Ensure that all external cables are securely attached to the external

connectors on your system before troubleshooting any external devices.

See Figure 1-1, Figure 1-2, and Figure 1-4 for the front- and back-panel

connectors on your system.

Troubleshooting the Video Subsystem

1 Check the system and power connections to the monitor.
2 Check the video interface cabling from the system to the monitor.

Troubleshooting a USB Device

Use the following steps to troubleshoot a USB keyboard and/or mouse.

For other USB devices, go to step 5.

1 Disconnect the keyboard and mouse cables from the system briefly and

reconnect them.

2 Connect the keyboard/mouse to the USB port(s) on the opposite side of

the system.

3 If the problem is resolved, restart the system, enter the System Setup

program, and check if the nonfunctioning USB ports are enabled.

4 Replace the keyboard/mouse with another working keyboard/mouse.

If the problem is resolved, replace the faulty keyboard/mouse.
If the problem is not resolved, proceed to the next step to begin

troubleshooting the other USB devices attached to the system.
