What is a valid step in launching ePSA diagnostics?

To launch ePSA (Enhanced Pre-boot System Assessment) diagnostics, powering up the system and pressing F12 multiple times during the boot process is the correct step. This action brings up the one-time boot menu, where you can select diagnostics options. ePSA is a built-in diagnostic tool that performs a series of tests to identify hardware issues before the operating system loads. By accessing the boot menu through the F12 key, users can initiate these diagnostics directly.

This process is crucial for troubleshooting system performance or hardware problems, as it allows users to quickly determine if a component is functioning correctly without needing to enter the BIOS settings or the operating system itself. The timing and method of pressing F12 are essential, as it must be done before the BIOS screen appears, ensuring access to the diagnostic options.
