Practical, no-fluff guides for checking HDD health, testing RAM, reading CPU temperatures, and decoding error codes — written for real users running Windows 11.
Each guide covers a specific hardware component with step-by-step instructions, tool recommendations, and common failure patterns.
Learn to identify early signs of hard drive failure using built-in Windows tools and third-party utilities before data loss occurs.
Read Guide →Understand how to run memory diagnostics, interpret test results, and determine whether faulty RAM is causing system crashes.
Read Guide →Find out what normal and dangerous CPU temperatures look like, and how to reduce thermal throttling on your processor.
Read Guide →Decode the beep sequences and numeric codes your motherboard produces during startup to pinpoint hardware faults quickly.
Read Guide →SMART attributes hold the story of your drive's health. Learn which values matter and what thresholds signal imminent failure.
Read Guide →Common Windows 11 stop codes and blue screen errors explained with practical steps to isolate the faulty hardware component.

The go-to utility for reading SMART data on Windows. Shows health status, temperature, and all attribute values in a clean interface. Supports NVMe and USB drives.
Boots independently of Windows to test RAM at a hardware level. More thorough than the built-in Windows Memory Diagnostic, especially for detecting intermittent errors.
Displays real-time temperatures, voltages, and fan speeds for CPU, GPU, and motherboard sensors. Useful for identifying thermal issues under load.
Built into Windows 11. Logs hardware errors, driver failures, and system warnings. Often the first place to look after an unexpected crash or blue screen.
