The hard-disk-based diagnostics contains tests that aid in troubleshooting all major components of the system. If it is not possible to run the server-based diagnostics or if the server-based diagnostics fails to reveal the source of a suspected hardware problem, run the hard-disk-based diagnostics by following these steps: 1. Turn on (or reboot) the system. 2. Press immediately after you see the following message: If you wait too long and the operating system begins to load into memory, let the system complete the load operation; then shut down the system and try again. Starting the diagnostics causes the Dell logo to appear on the monitor screen, followed by a message indicating that the diagnostics is loading.

The hard-disk–based diagnostics contains tests that aid in troubleshooting all
major components of the system. If it is not possible to run the server-based
diagnostics or if the server-based diagnostics fails to reveal the source of a
suspected hardware problem, run the hard-disk–based diagnostics by follow-
ing these steps:
1.
Turn on (or reboot) the system.
2.
Press <Ctrl><Alt><F10>
immediately
after you see the following
message:
3UHVV²´&WUO!´$OW!´(QWHU!²WR²HQWHU²WKH²6\VWHP²6HWXS²
SURJUDP³
If you wait too long and the operating system begins to load into memory,
let the system complete the load operation
; then shut down the system
and try again.
Starting the diagnostics causes the
Dell
logo to appear on the monitor
screen, followed by a message indicating that the diagnostics is loading.
Before the diagnostics loads, a program tests the portion of main memory
