Open Source C Hard Disk Health Check Software for Windows

Memtest86+ is a free, open-source, stand-alone memory diagnostic tool designed to thoroughly test system RAM beyond standard BIOS checks. It runs independently of any operating system, allowing it to access nearly all available memory without software or UEFI library limitations. Supporting x86, x86-64, and LoongArch64 architectures, Memtest86+ works on a wide range of modern and legacy hardware platforms. The tool can be booted directly via BIOS or UEFI, or through compatible bootloaders, making it highly flexible for troubleshooting unstable systems. It uses advanced testing algorithms specifically designed to detect intermittent, hard-to-find memory errors caused by cell interaction and hardware behavior. With ongoing development and community contributions, Memtest86+ remains a trusted solution for diagnosing memory-related system issues.
