When your Dell PC, monitor or tablet does not seem to be working correctly, diagnostic tools are available to help you identify what the issue may be, and provide troubleshooting steps to help resolve the issue.
Dell PCs and tablets come with pre-boot diagnostics (called 32-bit Diagnostics, PSA or ePSA), also newer computers have the Dell SupportAssist application installed to help you diagnose hardware problems.
It is recommended that you first run a diagnostic test to check for common errors with the hardware devices on your PC, monitor or tablet. You can choose to run a quick test, full test or even test a selection of hardware devices (custom test) on your Dell PC or tablet.
If the diagnostic test identifies a hardware issue, you can review troubleshooting suggestions that can help you resolve the problem, capture error codes that can help you fix your device or get replacement parts without calling technical support.
Dell's online diagnostics help you troubleshoot a problem, get automated fixes and order replacement parts. Online diagnostics installs Dell SupportAssist to help you troubleshoot your Dell PC.

This test will take approximately 10 minutes to complete. Run Quick Test or Run Stress Test.
Test a specific device or choose multiple hardware devices that you want to test. We will combine your selections into a single test to run. This test will take approximately 20 minutes or more to complete, depending on the selected hardware devices.
Run a full test to perform a thorough analysis of your Dell PC or tablet. This test runs a stress test on all the hardware devices on your Dell PC or tablet. This test will take approximately 40 minutes or more to complete. Run Full Test.
Dell PCs, tablets and monitors come with pre-boot or built-in diagnostics which can help diagnose hardware issues and capture error codes. Built-in or pre-boot diagnostics are run before the PC boots into the operating system. Running a built-in or pre-boot diagnostics does not require your PC to be connected to the internet.
Dell ePSA or PSA diagnostics are available on Dell laptops, desktops, servers and Windows-based tablets.
