HP PC Hardware Diagnostics is a Uniied Extensible Firmware Interface (UEFI) that allows you to run diagnostic 

tests to determine whether the computer hardware is functioning properly. The tool runs outside the 

operating system so that it can isolate hardware failures from issues that are caused by the operating system 

or other software components.
