HP PC Hardware Diagnostics review
Free Windows and UEFI diagnostics with stress tests, logs, and failure IDs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
HP PC Hardware Diagnostics is a free hardware-testing utility for HP desktop and notebook computers. It provides a Windows application for testing hardware while the operating system is active, alongside UEFI diagnostics that can run outside Windows. The toolset is suited to people diagnosing PC hardware faults, checking components, or preparing information for troubleshooting and HP support interactions. Tests cover processors, memory, storage, video memory, batteries, power, and system functions.
Its broad diagnostic coverage is the main reason to consider it. Fast and extensive system tests can assess core hardware, while processor stress testing, memory testing, storage checks with SMART support, and video memory testing address several common diagnostic needs. The UEFI version is particularly useful when Windows does not start, and bootable USB diagnostic media provides another way to launch the tools. Saved test logs and 24-digit failure IDs create structured information for follow-up troubleshooting.
The product fits HP PC owners who want no-cost diagnostics across both Windows and pre-boot environments. Its scope is narrower for people managing computers outside the HP desktop and notebook range, and the Windows application is intended for Windows systems. HP also states that available component tests can vary by computer model, so the exact diagnostic coverage depends on the PC. Choose it when free processor, memory, storage, video memory, and bootable diagnostics are priorities; look elsewhere when you need support beyond Windows or outside HP PCs.
