When to Use the Dell Diagnostics

contact Dell for technical assistance (see Dell Diagnostics
).
It is recommended that you print these procedures before you begin.
NOTICE: The Dell Diagnostics works only on Dell™ computers.
Enter system setup, review your computer's configuration information, and ensure that the device you want to test displays in
system setup and is active (see System Setup
).
Start the Dell Diagnostics from either your hard drive or from the Drivers and Utilities CD (an optional CD also known as the
ResourceCD). See Dell Diagnostics
.
Starting the Dell Diagnostics From Your Hard Drive
1. Turn on (or restart) your computer.
2. When the DELL™ logo appears, press <F12> immediately.
NOTE: If you see a message stating that no diagnostics utility partition has been found, run the Dell Diagnostics from
your optional Drivers and Utilities CD.

desktop. Then shut down your computer and try again.
