When your computer is booting randomly, freezing, or crashing, it might indicate a memory issue. However, you can use the Windows Memory Diagnostic tool to see if the problem is with the memory rather than changing your computer or memory.
If the memory passes the test, you can rule out this being the issue’s root. If it fails, you may need to replace one of your RAM modules.
This guide will show you how to run Windows memory diagnostic and check its results.
Let’s begin.
What is Windows Memory Diagnostic?
The memory diagnostic tool is a program that comes pre-installed with the Windows operating system from Microsoft. Its main objective is to help you find and diagnose problems with your computer’s Random Access Memory (RAM).
RAM is a crucial part of a computer that stores data that the Central Processing Unit (CPU) needs to carry out various operations.
So, What does Windows memory diagnostic do? Let’s find out:
1. Memory Testing
The tool runs several checks on the RAM in your computer to look for any potential issues or mistakes to get the Windows memory diagnostic results. These tests involve reading from and writing to various RAM locations to ensure the RAM operates correctly.
2. Identifying Memory Issues
You’ll get the Windows Memory Diagnostic results after the test if any problems are discovered. These issues could involve faulty memory sectors, data corruption, or other issues with memory.
3. Diagnostic Reports
It gives you a report that includes a summary of the tests’ findings, any memory-related issues, or if Windows memory diagnostic detected hardware errors.
4. Options for Advanced Testing
A basic test and an extended test are also available. The shorter basic test usually meets the needs of most users, whereas the extended test conducts a more thorough analysis of your RAM.
When Should You Use Windows Memory Diagnostic?
There are several indications to know when you should perform a memory diagnostic. Let’s go through them:
1. Frequent PC Crashes and Freezes
Frequent system freezes, or crashes are one of the most obvious indicators to use memory diagnostic. These sudden breaks in activity can be a sign of RAM problems.
Your computer may crash, become unresponsive, or even restart without warning when your RAM doesn’t function as it should. Using the diagnostic tool, you can determine whether the problem is with the RAM.

You now have two options for running the utility when your PC boots up. The first option is to restart your computer right away. The diagnostic will automatically run when the PC starts again.
Alternatively, you can schedule the utility to launch when your PC restarts.
When your computer restarts, the tool checks your memory immediately for any potential problems. The memory diagnostic tool launches by default in Standard mode, which includes eight consecutive memory tests.
Each of these tests uses a unique algorithm to look for different faults. The Standard tests can run until finished when Windows restarts.
You also have the option to use the F1 key at any time while the test is running. By doing this, you’ll be redirected to a different screen where you can choose the precise type of scan you want. The utility offers the Basic, Standard, and Extended scan options.
You can configure the Pass Count, which indicates how many times each test will be run. Two is the default value, which is usually sufficient for seeing any possible problems. Simply hit the F10 key to apply your options and begin the test after choosing your preferred option.
Method 2: Running from the Command Prompt
Running the memory diagnostic from the command prompt is easy. Here’s how to run Windows memory diagnostic from command prompt:
- Type “command prompt” in the search bar, right-click, and select “Run as administrator.”
- Type “mdsched” and press “Enter.”
- Click the “Restart now and check for problems(recommended)” option from the pop-up window.
Your computer will launch the memory diagnostic tool after restarting. This utility will start scanning the memory of your computer right away, and it’ll let you know if it finds any issues.
After the test, your computer will immediately reboot and return to the Windows desktop.
