GPU-Z
GPU-Z identifies graphics hardware and exposes the sensors it supports. TechPowerUp provides a portable executable with an optional installation.
HWiNFO
HWiNFO combines a component inventory with live sensor readings and reports. The current 64-bit and ARM64 editions are free for non-commercial use.
HWMonitor
HWMonitor groups available hardware sensors in one Windows window. Use CPUID’s free edition to observe temperatures, fan speeds and other supported readings.
CrystalDiskInfo
CrystalDiskInfo reads health information reported by supported hard drives and SSDs. It helps interpret storage warnings, without repairing a damaged drive.
MSI Afterburner
MSI Afterburner monitors graphics hardware and offers supported tuning controls. You can use it to watch a game without changing clocks or voltage.
Speccy
Speccy presents a hardware summary and more detailed component pages. Its free home edition can save results for a support request or an upgrade discussion.
Process Explorer
Microsoft Sysinternals’ detailed process viewer for investigating running applications, open handles and loaded libraries.
Process Monitor
Process Monitor records detailed file, registry and process events. Use a short, filtered capture to investigate a reproducible application problem.
Core Temp
Core Temp focuses on processor temperature rather than a full hardware inventory. It offers a compact window and configurable readings in the Windows notification area.
OCCT
OCCT combines selectable hardware tests, monitoring and benchmarks. Its free Personal edition is for non-commercial use and limits individual tests to one hour.
FurMark
FurMark creates a sustained graphics workload for checking GPU behavior. Its benchmark score is useful when the test settings are recorded alongside it.
RAMMap
RAMMap breaks physical memory usage into views for processes, cached files and allocation types. Microsoft Sysinternals supplies it as a portable diagnostic utility.
LatencyMon
LatencyMon records system timing and driver activity that may help explain clicks or gaps in audio. It gives you evidence to investigate, rather than an automatic repair.
HDDScan
HDDScan combines storage information, SMART reports and several drive tests. Select the test deliberately: its Erase mode overwrites data and is not a routine health check.
smartmontools
smartmontools provides command-line storage diagnostics and configurable monitoring. It is suited to users who want detailed device reports rather than a simplified health badge.
Guides
How should you monitor CPU and GPU temperatures?Identify the component and sensor first. Record idle and working readings under comparable conditions before deciding whether a temperature is unusual.How do you find the specifications of your Windows PC?Collect the details you need for a specific decision. A support request, a driver download and a memory upgrade may require different information.
