手順

Dell's online diagnostic test helps you scan the computer for issues, recommends troubleshooting steps, get automated fixes, and order replacement parts. The online diagnostics test uses SupportAssist to scan the hardware.

NOTE: SupportAssist is preinstalled on all Windows computers shipped out of the Dell factory. If SupportAssist is not preinstalled, browse to the SupportAssist for home PCs page to download and install SupportAssist. Browse to the SupportAssist for Home PCs support site, for the latest Release Notes and User’s Guide, which provide information such as Minimum PC requirements and SupportAssist capabilities and Dell service plans.
NOTE: You must have administrator privileges to install SupportAssist.
NOTE: The online part replacement service depends on the warranty coverage of your Dell computer. This service is available in select countries.
NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminal when the diagnostic tests are performed.

You may experience a time when your computer may not run as smoothly as it once did. File corruption, a virus, spyware, malware, or a hardware failure could cause this issue. Using the online diagnostic test helps identify any issues.

  1. Go to Dell.com/support.
  2. Identify your Dell computer.
    1. Click Download & Install SupportAssist to auto-detect your Dell product. Follow the on-screen instructions to install Dell SupportAssist.
    2. Or, enter the Service Tag, Express Service Code, or the Serial number of the Dell computer and click Search.
    3. Or, click Browse all products to manually select your Dell product from the catalog (Figure 1).

  4. Choose to run one of the diagnostic tests.
    1. Run a quick Test - Run a quick test when you notice issues such as the system is slow or does not respond, hard drive errors, system is making noise, system is freezing or randomly restarting, files do not open and so on. The quick test includes components that are most likely to cause issues, such as hard drive or memory. If an error is detected, we will fix it automatically, suggest troubleshooting steps, recommend further tests or help you get compatible replacement parts. A quick test takes approximately 10 minutes to complete (Figure 3).

    2. Run a full Test - Run a full test to perform a thorough analysis of your Dell computer or tablet. This test runs a stress test on all the hardware devices on your Dell computer or tablet. This test takes approximately 40 minutes or more to complete (Figure 4).

    3. Run a Custom Component Test - Custom Component Test allows you to select one or more devices that you want to test. We will combine your selection into a single test to run. This test takes approximately 20 minutes or more to complete, depending on the selected hardware devices (Figure 5).
