Important boot requirement

Secure Boot must currently be disabled.

Blackwire Hardware Diagnostics is a custom UEFI application. The current release is not yet signed for Microsoft Secure Boot, so you will normally need to disable Secure Boot temporarily before starting it.

Before changing Secure Boot settings, verify your BitLocker or Windows Device Encryption recovery key and suspend protection when appropriate.

  • Save or verify the recovery key first.
  • Suspend BitLocker protection before firmware changes when possible.
  • Do not clear the TPM.
  • Do not delete Secure Boot or platform security keys.
  • Do not change unrelated BIOS or UEFI settings.
  • Re-enable Secure Boot after testing when appropriate.

Two editions

Free diagnoses the hardware. Business documents and manages the job.

The diagnostic engine is not deliberately weakened to force an upgrade. Free is a real diagnostic tool; Business adds the professional workflow around it.

Major improvements

Hardware Diagnostics has grown into a much more complete native UEFI diagnostic environment.

The newer releases focus on better hardware detection, clearer live evidence, safer storage handling, stronger graphics testing, better results, broader resolution support, and more useful professional workflow.

Improved hardware detection

Inventory and identification have been expanded across CPU, memory, motherboard, storage, graphics, PCI Express hardware, firmware graphics, and system hardware.

Expanded graphics diagnostics

Current builds add GPU/iGPU identification, PCIe graphics-link inspection, PCIe error evidence, option-ROM inspection, UEFI GOP validation, framebuffer testing, and longer technician-selectable graphics verification.

Improved memory diagnostics

Live memory testing now communicates installed memory, write and verification throughput, detected errors, and hardware information where firmware exposes reliable data.

Improved storage diagnostics

Storage detection and workloads have been refined across NVMe, SATA, and block devices. Optical CD/DVD/Blu-ray drives are automatically excluded from HDD/SSD read workloads.

Better stress-test interface

The live stability view now brings CPU workload, memory throughput, supported temperature and power telemetry, elapsed/remaining time, completion, graphs, verification, and errors into one screen.

Better resolution support

The UEFI interface has been refined across common firmware modes from 800×600 through 4K, with more appropriate layout, navigation, results panels, and text placement.

Improved results guidance

Results separate failures, warnings, skipped, unsupported, and not-run items more clearly. Detailed result guidance explains what was checked, why attention is needed, possible causes, and practical next steps.

Business workflow improvements

Business adds customer information, refined reporting, saved diagnostic evidence, reusable presets, category selection, repeat/loop counts, and stronger failure retention across repeated runs.

Current-generation validation

Actively tested and refined on modern hardware and UEFI platforms.

Ongoing development and field testing include current Intel and AMD platforms, DDR4 and DDR5 systems, NVMe and SATA storage, integrated and discrete graphics, current PCIe platforms, recent UEFI firmware implementations, and high-resolution GOP display modes.

Compatibility work on newer releases has specifically targeted hardware detection, graphics diagnostics, storage handling, UEFI behavior, display scaling, and modern platform differences.

This is active compatibility testing, not a guarantee that every motherboard, firmware build, or hardware combination in existence is supported.

  • Current Intel and AMD platforms
  • DDR4 and DDR5 memory systems
  • NVMe and SATA storage
  • Integrated and discrete graphics
  • Current PCIe and UEFI implementations
  • 800×600 through 3840×2160 UEFI GOP modes

70Standard automatic tests
73Extended automatic tests

Free gets the automatic profiles.

Core, Standard, and Extended are part of the diagnostic engine. Business adds reusable technician presets, Preset Builder, and repeat/loop workflows for people who need to save and rerun custom plans.

  • Core — essential first-pass health check
  • Standard — recommended repair-bench diagnostic
  • Extended — broader non-destructive validation
  • Business — build, save, and repeat custom diagnostic plans

Hardware coverage

Test the major hardware areas from one bootable tool.

Tests are capability-aware: unsupported or unavailable measurements are reported as such rather than replaced with invented readings.

System and firmware

System inventory, firmware variables, SMBIOS information, PCI/PCIe evidence, boot configuration, and firmware integrity checks.

Processor

Identification, known-answer integer/floating-point/vector work, cache integrity, multicore execution, timer behavior, and related CPU checks.

Memory

Firmware memory-map validation, dynamic memory integrity, address-path checks, write/verify throughput, errors, and memory information where available.

Storage

NVMe, SATA, and supported block-device checks including health evidence, latency, read integrity, throughput, and thermal observations where supported.

Graphics

GPU/iGPU identification, PCIe evidence, graphics option-ROM inspection, UEFI GOP mode validation, display identification, and framebuffer pattern verification.

Security and platform

TPM and supported security/firmware checks that report what the platform exposes without clearing keys or changing protected configuration.

Live diagnostic evidence

See what is running, what was measured, and what comes next.

The current run screen combines the active workload, measurements, overall progress, next test, activity history, attention items, elapsed time, estimate, and status controls.

Optical CD/DVD/Blu-ray devices are excluded from HDD/SSD read workloads so an optical drive or inserted disc cannot accidentally enter long storage-read testing.

CPU + memory stability

Stress testing now has a purpose-built live dashboard.

Longer stability work can show CPU workload, memory verification throughput, supported temperature and power telemetry, elapsed and remaining time, completion percentage, verification counts, errors, and live graphs.

  • CPU workload and memory verification
  • 10 / 30 / 60 / 120 minute and continuous modes where available
  • Elapsed and remaining time
  • Completion percentage
  • Live graphs
  • CPU temperature and power where firmware exposes useful telemetry
  • CPU and memory error counters
  • Technician-controlled stop with prior failures retained

Use adequate cooling and supervision. Stop for any unsafe physical condition. Missing sensor data is reported as unsupported rather than guessed.

Improved results

Warnings and failures now lead to useful detail instead of a color alone.

The Results page separates passed, warning, failed, not-run, skipped, unsupported, and locked outcomes. Select a result to see the observed evidence, what was checked, likely causes, and practical next steps.

Professional reporting — Business

Document what was tested, what passed, and what needs attention.

Business reporting separates actual failures, warnings, skipped tests, unsupported items, and tests not included in the selected plan so a customer or technician can understand what the report does—and does not—say.

Business documentation

  • Customer and system identification
  • PDF and diagnostic report output
  • Persistent logs and saved evidence
  • Failure, warning, skipped, unsupported, and not-run distinctions
  • Recommended next steps and technician-facing details
  • Saved screenshots when evidence needs to be captured

Free: The same diagnostic purpose and on-screen results, without the Business reporting, logging, screenshot, customer-info, or preset workflow.

Who it is for

Useful on a repair bench, in IT, or on a system you are troubleshooting yourself.

Testing outside Windows helps separate hardware failures from Windows problems, drivers, applications, malware, corrupted installations, and other operating-system issues.

Repair and service

PC repair technicians, computer refurbishers, electronics recyclers, hardware resellers, and system builders can test systems before repair, resale, or return.

IT and MSP work

IT departments, MSPs, field technicians, and system administrators can run repeatable checks without relying on the installed operating system.

Advanced home users

Use Free to investigate a computer that may have CPU, memory, storage, graphics, firmware, or stability problems without buying a professional workflow package.

Boot media and requirements

Designed for compatible x64 UEFI PCs.

Hardware availability and firmware interfaces determine what can be identified or tested. Unsupported information is reported honestly instead of being invented.

Frequently asked questions

Common questions before you start.

Is the Free edition a trial?

No. Free v1.7.16 contains the real diagnostic engine and on-screen results. It omits the Business customer-info, reporting, persistent logging, screenshot, preset, and repeating-workflow features.

Are the hardware tests different in Business?

Business uses the same current diagnostic direction and hardware-test purpose. It adds professional workflow and documentation rather than intentionally weakening Free to force an upgrade.

Are older Hardware Diagnostics versions included?

Yes. The current Free and Business download packages include the previous Hardware Diagnostics versions as well, so an older build remains available when compatibility or rollback is useful.

Does it run inside Windows?

No. It boots through compatible 64-bit UEFI firmware and runs independently from Windows or another installed operating system.

Why must Secure Boot be disabled?

The current UEFI application is not yet signed for Microsoft Secure Boot. Disable Secure Boot temporarily when required, keep recovery keys available, and re-enable it after testing when appropriate.

Does the program erase or format drives?

Normal storage diagnostics are designed to be read-only and do not intentionally erase, overwrite, format, partition, repair, or modify user files.

What are the automatic profiles?

Core currently includes 31 automatic tests, Standard 70, and Extended 73. The exact tests that can run still depend on the detected hardware and firmware capabilities.

Does it fully test every graphics card feature or VRAM?

No. It includes UEFI graphics and framebuffer diagnostics, identification, link/error evidence, and supported GOP checks. It does not claim to replace every vendor-specific GPU diagnostic or a complete dedicated VRAM test.

What happens when a sensor is unavailable?

The program reports unsupported or unavailable telemetry rather than inventing a temperature, power, ECC, or other reading that the platform does not expose.

Can a computer still have a problem after passing?

Yes. A pass means that specific test did not detect a fault during that run. Intermittent problems may require repeated, extended, or manufacturer-specific testing.

Are current builds activation-locked?

No. The current Free and Business releases do not use Blackwire product-key activation. A future Secure Boot-signed generation may use normal Blackwire licensing.

Current releases

Free v1.7.16 and Business v1.7.15 are available now.

The current release has been tested extensively on modern-generation hardware and UEFI systems, with ongoing field testing used to refine compatibility and diagnostic behavior across newer platforms. Previous Hardware Diagnostics versions remain included in the current download packages.
