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 imaging messaging, especially after installing an operating system or reconfiguring your system's hardware, check for the following conditions. • If you boot the system to the BIOS boot mode after installing an operating system from the UEFI Boot Manager, the system will hang. The reverse is also true. You must boot to the same boot mode in which you installed the operating system. See "Using the System Setup Program and UEFI Boot Manager" on page 39. • Invalid memory configurations could cause the system to halt at startup without any video output. See "Expansion Cards and Expansion-Card Risers" on page 88. For all other startup issues, note the system messages that appear onscreen. See "System Messages" 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 and Figure 1-3 for the front- and back-panel connectors on your system. Troubleshooting Your System 129

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 imaging messaging,
especially after installing an operating system or reconfiguring your system’s
hardware, check for the following conditions.
•
If you boot the system to the BIOS boot mode after installing an operating
system from the UEFI Boot Manager, the system will hang. The reverse is
also true. You must boot to the same boot mode in which you installed the
operating system. See "Using the System Setup Program and
UEFI Boot Manager" on page 39.
•
Invalid memory configurations could cause the system to halt at startup
without any video output. See "Expansion Cards and Expansion-Card
Risers" on page 88.
For all other startup issues, note the system messages that appear onscreen.
See "System Messages" 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 and Figure 1-3 for the front- and back-panel connectors
on your system.
