Two or more runs of the HP UEFI hardware diagnostics may report all passes.
It has good accuracy except RAM and perhaps the motherboard.
For more thorough RAM testing run Memtest86+ as needed.
"'Memtest86+ is a stand-alone memory tester for x86 and x86-64 architecture computers.
It provides a more thorough memory check than that provided by BIOS memory tests."'
Memtest86+ | The Open-Source Memory Testing Tool
Once you've established that there is no RAM problem the HP Windows hardware diagnostics can be used.
