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 and ePSA), also newer computers has 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.
