Troubleshooting Your System
Safety First—For You and Your System
CAUTION: Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service
and support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came
with the product.
Troubleshooting System Startup Failure
If your system halts during startup prior to video output, especially after
installing an operating system or reconfiguring your system’s hardware, check
the memory configurations. Invalid memory configurations could cause the
system to halt at startup without any video output. See "System Memory" on
page 66.
For all other startup issues, note the system messages that appear onscreen.
See "System Messages" on page 35 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 1-2 and Figure 1-5 for the front-panel and back-panel connectors
on your system.
Troubleshooting a NIC
1 Run the appropriate online diagnostic test. See "Running the System
Diagnostics" on page 105.
2 Restart the system and check for any system messages pertaining to the
NIC controller.
