Your computer depends on RAM to run fast and smooth. If RAM has errors, your computer may freeze, crash, or run very slow. Many people do not know how to test RAM for errors. Windows itself has a built-in tool that can help you find memory problems. This tool is called Windows Memory Diagnostic. It is simple to use and very useful when you want to do a RAM test.
RAM stands for Random Access Memory. It stores short-term data that your computer needs to open apps and run programs. If there are problems in RAM, you may see blue screen errors, sudden restarts, or apps closing without warning. Doing a RAM test helps you check RAM issues before they get worse. With Windows Memory Diagnostic, you can scan and find hidden problems.
To start the memory diagnostic, press the Windows key + R on your keyboard. This will open the Run box. Type mdsched.exe and press Enter. You will see a new window pop up with two options:
If you choose the first option, your PC will restart right away and begin the RAM test. If you choose the second, the RAM test will run the next time you turn on your computer.
After your computer restarts, the Windows Memory Diagnostic tool will begin to check RAM issues. The screen will show the progress of the scan and if any errors are found. You do not need to do anything while the test is running. Just let it finish.
The test may take some time depending on the size of your RAM. Usually, it takes between 10 to 30 minutes. During this time, you cannot use your computer, so make sure you save your work before starting the memory diagnostic.
When the RAM test is complete, your computer will restart again. After logging into Windows, you will see the test results in the notification area. If errors are found, you should take action. If no errors are found, it means your RAM is working fine.
Sometimes, Windows may not show results right away. In that case, you can check them manually. To do this, open the Event Viewer. Press the Windows key + X and select Event Viewer. Then go to Windows Logs > System. Look for a log entry named "MemoryDiagnostics-Results." This will tell you if there were any problems in your RAM test.
If the memory diagnostic shows errors, you may need to replace your RAM. Before doing that, make sure the RAM sticks are seated properly. You can also try cleaning the slots and testing each RAM stick one by one. If problems continue, it is better to buy new RAM. Faulty RAM can cause serious damage to your system over time.
RAM is one of the most important parts of your computer. When it fails, your system becomes unstable. Running a RAM test with Windows Memory Diagnostic is the best way to check RAM issues quickly. This tool is free, easy, and built into every version of Windows. By testing your RAM regularly, you can keep your computer fast and avoid sudden problems.
