HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:-

and then perhaps obtain an operating system to install.

We would like more details please.
