Starting the Dell Diagnostics From the Drivers and Utilities Media
Before running the Dell Diagnostics, enter the system setup program (see
your
Service Manual on the Dell Support website at support.dell.com) to
review your computer’s configuration information, and ensure that the device
you want to test is displayed in the system setup program and is active.
1 Insert the Drivers and Utilities media into the optical drive.
2 Restart your computer.
3 When the DELL logo appears, press <F12> immediately.
NOTE:
Keyboard failure may result when a key is held down for extended
periods of time. To avoid possible keyboard failure, press and release <F12> in
even intervals to open the Boot Device Menu.
If you wait too long and the operating system logo appears, continue to
wait until you see the Microsoft Windows desktop, and then shut down
your computer and try again.
4 When the boot device list appears, use the up- or down- arrow keys to
highlight CD/DVD/CD-RW Drive then press <Enter>.
NOTE:
Using the one-time boot menu changes the boot sequence for the
current boot only. Upon restart, the computer boots according to the boot
sequence specified in the system setup program.
5 Press any key to confirm that you want to start from the CD/DVD.
If you wait too long and the operating system logo appears, continue to
wait until you see the Microsoft Windows desktop, and then shut down
your computer and try again.
6 Type
1 to Run the 32 Bit Dell Diagnostics.
7 At the Dell Diagnostics Menu, type 1 to select Dell 32-bit Diagnostics for
Resource CD (graphical user interface).
8 Press <Tab> to select Test System and then press <Enter>.
NOTE:
It is recommended that you select Test System to run a complete test
on your computer. Selecting Test Memory initiates the extended memory test,
which can take up to thirty minutes or more to complete. When the test
completes, record the test results and then press any key to return to the
previous menu.
