How to Diagnose Memory Problems on Windows Computers

May 21, 2024

Like any other operating system, Windows might have some hardware-related issues as well. Luckily, there is a built-in hardware diagnostic tool called Windows Memory Diagnostic which can help users identify and troubleshoot any hardware issues related to RAM (Random Access Memory) in their computers.

Regular diagnostics can help ensure the system function well, prevent minor issues from escalating into major problems, and improve the overall performance of the computer. In this WiseCleaner article, we will guide you through the steps of diagnosing memory issues by using Windows Memory Diagnostics on Windows 11.

Step 1. Run Windows Memory Diagnostic

Press the Win key + R on your keyboard to open the Run dialog box. Then type “mdsched.exe” and press Enter or click on the OK button.

Step 2. Begin the diagnostic process

You will be presented with two options. Choose the option which best suits your needs.

  • Restart now and check for problems (recommended): the computer will restart immediately, and the Memory Diagnostics tool will run before the system boots up to scan for errors.
  • Check for problems the next time I start my computer: the Memory Diagnostics tool will run automatically the next time you restart your computer. If you do not want to interrupt your current work session, this one is extremely useful.

Step 3. Check the results

After scanning, the Windows Memory Diagnostic tool will display the results. If there are any problems, you can address them by the information provided.
