Running hardware diagnostics on Windows 11 is a simple way to ensure your computer’s components are functioning properly. This process involves using built-in tools to check for issues with hardware like your CPU, RAM, or hard drive. In just a few steps, you can diagnose potential problems and decide if professional repairs are needed.
How to Run Hardware Diagnostics on Windows 11
Windows 11 offers some built-in tools to help you test and troubleshoot hardware issues. By following these steps, you’ll be able to pinpoint any problems and keep your computer running smoothly.
Step 1: Open Windows Security
Start by navigating to the Windows Security settings to access the Device Performance & Health report.
Open the Start menu, type “Windows Security,” and select it from the list. Once in, you’ll find an overview of your system’s health.
Step 2: Access Device Performance & Health
Check your device’s status by examining its performance and health metrics.
In the Windows Security menu, click on “Device Performance & Health.” This section provides a basic overview, highlighting any detected issues.
Step 3: Run the Memory Diagnostic Tool
Use this tool to check if your RAM is causing any problems.
Press Windows + R, type “mdsched.exe,” and hit Enter. Choose to either restart now or check the next time you start your computer, and let the tool do its work.
Step 4: Use the Command Prompt for More Tests
You can run additional checks using the Command Prompt.
Open the Start menu, type “cmd,” and run it as an administrator. You can use commands like “chkdsk” to check your hard drive or “sfc /scannow” to repair system files.
Step 5: Analyze the Results
Once the tests are done, review the results to decide on any necessary actions.
After each test, you’ll receive a report. Pay attention to any errors or warnings that suggest hardware issues.
After completing these steps, Windows 11 will provide you with detailed reports on your hardware’s condition. If any problems are detected, you’ll know whether you need to replace components or take further action.
