How to Run the Dell Legacy 32-bit Diagnostics Utility



Older (legacy) Dell computers ship with a utility partition on the hard drive that contains the legacy 32-bit Dell Diagnostic Utility, to help you determine any hardware issues.

Note: For personal computers bought after Jan 1, 2009, please refer to Dell Knowledge Base article Resolve Hardware Issues With Built-in and Online Diagnostics (ePSA or PSA Error Codes).

To run the built-in diagnostics, perform the following steps:

  1. Restart the computer.
  2. As the computer boots, press F12 when the Dell Splash Screen appears.
  3. When the Boot menu appears, highlight the Boot to Utility Partition option, or the Diagnostics option and then press Enter to start the legacy 32-bit Dell Diagnostics.
  4. Press the Tab key to highlight Test System Press Enter to continue to the legacy 32-bit Diagnostics.
    Note: In some cases the PSA Diagnostics will run first. When you receive an error during the PSA diagnostics, refer to Dell Knowledge Base article Resolve Hardware Issues With Built-in and Online Diagnostics (ePSA or PSA Error Codes). You will be given the option to go into the 32-bit Diagnostics, press the N (No) or Y (Yes) key to continue into the legacy 32-bit Diagnostics, when you are asked to Continue Memory Tests.
    • Express Test will run a quick test of devices in the system. This typically can take 10-20 minutes.
    • Extended Test performs a thorough check of devices in the system. This typically can take an hour or more.
    • Custom Test used to test a specific device or customize the tests to be run. Exit to MS-DOS will exit the diagnostics to a command prompt.
    • Symptom Tree. This option lists the most common symptoms and allows you to select tests based on those symptoms.
      Note: Express Test is the only test that will not require user involvement.

Note: When the diagnostics produces an error, make a note of the error and Contact Technical Support for further assistance.
