Enhanced Pre-Boot System Assessment (ePSA) Diagnostics

The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device groups allowing you to:

•Run tests automatically or in an interactive mode

•Repeat tests

•Display or save test results

•Run thorough tests to introduce additional test options to provide extra information about the failed device(s)

•View status messages that inform you if tests are completed successfully

•View error messages that inform you of problems encountered during testing

CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid results or error messages.
