Running the System Diagnostics
Unlike many diagnostic programs, Dell’s system diag- nostics helps you check the computer’s hardware without any additional equipment and without destroying any data. By using the diagnostics, you can have confidence in the computer system’s operation.

CAUTION: Use the system diagnostics to test only Dell computer systems. Using this program with other computers may cause incorrect computer responses or result in error messages.
