Hardware involved with your problem is not detected by a memory test or drive test. However if those (or other) hardware has a problem, it is more likely to be found in the system (event) logs.

The only diagnostic that will test hardware relevant to your problem is HP's comprehensive diagnostics.

Why a difference between execution time of two machines? Those numbers (reason for the difference) may be found in BIOS settings. Those numbers may also be reported by HP's comprehensive diagnostics.

All those tests that Dar512 has recommended are in comprehensive diagnostics.

There is little to nothing useful in Windows diagnostics because Windows is designed to work around and avoid hardware failures whenever possible. However if Windows has seen a hardware failure, then that is stored and reported in system logs or is obvious in Device manager. Windows is a bad tool for hardware diagnosis.

Once a manufacturer's comprehensive diagnostic says OK, then move on to other suspects - which is not hardware.
