You can choose to run quick tests, full tests, and even test a variety of hardware devices (custom tests) on a Dell PC or tablet. It is recommend that you first run diagnostic tests to check for common errors with hardware devices on your PC, monitor, or tablet. Diagnostic tools are available to help you identify what the issue may be, and provide troubleshooting steps to help resolve the issue.ĭell Computers and tablets are equipped with pre-boot diagnostics (called 32-bit diagnostics, PSA, or ePSA), and newer computers have the Dell Support Assist application installed to help you diagnose hardware problems. When your Dell PC, monitor or tablet does not seem to be working correctly, running Dell diagnostics should be the first resort.
