Because the tool needs exclusive access to your RAM, it must run before Windows fully loads. How to Use Windows Memory Diagnostic | Microsoft Surface

: Checks if writing data to one memory cell unintentionally affects the state of an adjacent cell. what does windows memory diagnostics tool check

If you choose the extended option, the tool digs deeper into hardware-level physics: Because the tool needs exclusive access to your

Memory cells that are permanently stuck at "0" or "1" and cannot change state. : Adds more complex algorithms like LRAND (Random

: Adds more complex algorithms like LRAND (Random pattern test), Stride6 (Moving inversions), and WMATS+ .

The first thing the tool did was a fast, low-level scan. Imagine a librarian checking if all the books are on the correct shelves, but at lightning speed. The tool wrote a simple pattern of data—all 1s and 0s—into every single memory address. Then it read that data back. If a memory cell that was supposed to hold a "1" returned a "0," the test failed immediately. This is called a . It catches the most obvious failures: completely dead memory cells, cells that are "stuck" at a certain value, or severe addressing issues where data gets written to the wrong location. For Leo’s problem, this test passed with flying colors. The issue was more subtle.

If your computer is suffering from the "Blue Screen of Death" (BSOD), freezing randomly, or crashing applications, the culprit is often faulty RAM (Random Access Memory). The (WMD) is a built-in utility designed to test your computer's memory for errors.
