Maintaining your PC’s health is crucial for optimal performance and longevity. Just like cars need regular check-ups, your computer benefits from periodic diagnostics to identify and resolve potential issues before they escalate. Windows operating systems come equipped with a range of built-in diagnostic tools designed to help you keep your system running smoothly. This guide will walk you through how to run diagnostics on your PC, utilizing these native Windows features and exploring other helpful options.
Understanding Windows Diagnostic Tools
Windows 10 and Windows 11 offer several built-in tools to diagnose and troubleshoot various PC problems. These tools are designed to be user-friendly and can help identify issues related to hardware, software, and system performance. Among the most useful are the Windows Troubleshooters, the Windows Memory Diagnostic tool, and the Reliability and Performance Monitors. Additionally, many hardware manufacturers provide their own diagnostic utilities, and a plethora of third-party diagnostic applications are available to cater to more specific needs. Understanding how to access and utilize these resources is the first step in effectively diagnosing your PC.
Using Windows Troubleshooter for Common Issues
The Windows Troubleshooter is a built-in utility designed to automatically identify and resolve common computer problems. It covers a wide array of potential issues, from internet connectivity and audio problems to printer malfunctions and Bluetooth connectivity. Running a troubleshooter is a straightforward process:
-
Accessing the Troubleshoot Menu:
- For Windows 11: Navigate to Settings by clicking the Start Menu and selecting the gear icon. Then, click on System, and finally, select Troubleshoot.
- For Windows 10: Open Settings via the Start Menu. Click on Update & Security, and then choose Troubleshoot from the left-hand menu.

Windows will then run the selected troubleshooter, automatically detecting and attempting to fix any identified problems. Follow any on-screen prompts and allow the troubleshooter to complete its process. If a problem is found, the troubleshooter will often provide recommended solutions or automatically apply fixes.
Checking Your RAM with Windows Memory Diagnostic
Random Access Memory (RAM) issues can manifest as system sluggishness, frequent program crashes, or even the dreaded “blue screen of death.” The Windows Memory Diagnostic tool is specifically designed to test your computer’s RAM for errors. If you suspect your RAM might be failing, running this diagnostic is a prudent step:
-
Opening Windows Memory Diagnostic: Click on the search bar in your taskbar (or press the Windows key + S) and type “Windows Memory Diagnostic.” Select the “Windows Memory Diagnostic” app from the search results to open it.

-
Running the Memory Test: You will be presented with two options: “Restart now and check for problems (recommended)” or “Check for problems the next time I start my computer.” It’s generally recommended to restart immediately to run the test promptly. Select your preferred option.

Your computer will restart and automatically launch the Windows Memory Diagnostic tool. The tool will perform a series of tests on your RAM. This process may take several minutes to complete. Once finished, your computer will reboot back into Windows.
-
Reviewing the Results: The results of the memory diagnostic test are logged in the Event Viewer. To access the Event Viewer, search for “Event Viewer” in the taskbar search and open the application. In the Event Viewer, navigate to Windows Logs > System. Look for entries with the source “MemoryDiagnostics-Results.” These entries will detail the outcome of the memory test, indicating whether any errors were detected. If errors are found, it might be time to consider replacing your RAM modules.
Monitoring System Reliability and Performance
For a broader overview of your system’s health and performance, Windows provides the Reliability Monitor and Performance Monitor tools.
-
Reliability Monitor: This tool tracks software and hardware problems over time, presenting a visual history of system stability. It assigns a stability index to your system and charts events like application failures, Windows errors, and hardware failures. To access it, search for “Reliability Monitor” or “View reliability history” in the taskbar search. Reviewing the Reliability Monitor can help pinpoint recurring issues or software conflicts that might be affecting your PC’s performance.

-
Performance Monitor: This is a more advanced tool that provides real-time and logged data on system performance metrics, including CPU usage, memory usage, disk activity, and network performance. You can search for “Performance Monitor” to launch it. While more complex, Performance Monitor can be invaluable for identifying bottlenecks and understanding how your system resources are being utilized.
Exploring Other Diagnostic Options
Beyond the built-in Windows tools, remember that many PC and component manufacturers offer their own diagnostic utilities. For example, Intel provides the Intel Processor Diagnostic Tool to assess the health and performance of Intel CPUs. Dell, HP, and other major PC brands often include pre-installed diagnostic software specific to their hardware. Check your manufacturer’s website or support documentation to see if such tools are available for your PC.
Furthermore, numerous third-party diagnostic software applications offer a wide range of features, from comprehensive hardware testing to in-depth system analysis. When considering third-party tools, ensure you download them from reputable sources to avoid malware.
