HP typically provides the 'HP PC Hardware Diagnostics UEFI' tool, which can be accessed by pressing F2 during startup. This utility allows you to perform comprehensive tests on components like memory, hard drive, processor, and more. Running these diagnostics can help pinpoint the exact hardware component that is failing and causing the 0021 error.
