Hardware Diagnostics is an application for diagnosing hardware issues that can provide a report covering a wide range of technical aspects and provide suggestions for resolving issues with both the hardware and the memory.

Hardware problems can typically show in the form of Blue Screen of Death (BSOD), system crashes, abnormal temperatures, or slow system response times. In a worst-case scenario, these unaddressed hardware problems can lead to total system failure.

Does Windows 10 have a hardware diagnostic tool?

Windows 10 hardware diagnostic tools can be quite a chore to use unless one has prior knowledge of the OS and these tools.

The OS has a few native hardware diagnostic tools that we will show you how to use. In addition, PC manufacturers also add their custom ones. Depending on the ease of use and access of these tools, the process can be simple or difficult.

This is where the hardware diagnostics come in. PCs come with pre-installed diagnostics tools to prevent, detect, and/ or fix any hardware problems that may occur over the PC’s lifespan.

These tools can be OS-exclusive, PC manufacturer-exclusive, or even BIOS-exclusive. In addition, depending on the scope of these tools, they may be directed towards a specific hardware component or even all of them.

How can I run hardware diagnostics on Windows 10?

1. Use the Performance Monitor tool

The simplest and most handy way to diagnose your hardware status on your PC is the Performance Monitor tool that anyone can access. The instructions below shows you how to use it.

1. Access Performance Monitor

Press the Windows key and search for Performance Monitor. Open the top result.

From the left pane menu, expand the Data Collector Sets section. Click on the System option.

Right-click System Diagnostics and select Start to begin system diagnostics tests.

Now, from the left pane menu, expand the Reports section, expand the System section, and open the System Diagnostics section.

You will find the generated system diagnostics test report here. Simply double-click the report to view it. Check out your PC’s Diagnostic Results.

Look out for any failures in the Basic System Checks section. If no problems are detected by the Windows 10 hardware check, it’s more than likely that your PC is doing great.

2. Use the Windows Memory Diagnostic app

1. Press Windows and search for Windows Memory Diagnostic. Click the first result to open it.
   
2. Select the option Restart now and check for problems (recommended).
   
3. Let the PC restart. Once the PC is restarted, the memory diagnostic scan will automatically begin. Wait for the process to finish. Your PC will reboot automatically afterward.
   
4. After logging in, the results will be displayed on the desktop. In case the test results fail to show on the screen automatically, use the Event Viewer app to check the scan results. Thus, press Windows and search for Event Viewer in the Search bar. Open the first app.
   
5. From the left pane menu, expand the Windows Logs section and click on the System option.
   
6. In the right pane Actions menu, expand the System section. Click on the Find… option.
   
7. In the text field, type MemoryDiagnostic and click on Find Next to look for the memory diagnostic scan log.
   
8. View the results of the memory diagnostic scan in the General tab.
   

Unless you find any errors, your PC’s RAM is not a cause for concern. However, if you do find any errors, see if they can be resolved without the need for replacing your RAM. If that’s not possible, replace the RAM.

Check out more details on the Windows Memory Diagnostic Tool and how it can help keep your PC’s memory in check.

3. Run a CHKDSK scan to check for bad sectors

NOTE

The CHKDSK scan can end up taking a lot of time. A good estimate is probably around 2-3 hours.

1. Press the Windows key and search for CMD in the Search bar. Choose the Run as administrator option under the result.
   
2. Type the following command and run it by pressing Enter. A prompt will appear asking you to schedule the scan on the next restart. Type Y and then press Enter: CHKDSK /R
   
3. Restart your PC. Once the PC restarts, the CHKDSK scan will begin automatically. Wait for the scan to complete.
4. Once the scan is complete and you log in, press Windows and search for Event Viewer in the Search bar. Open the app.
   
5. From the left pane menu, expand the Windows Logs section and click on the Application option.
   
6. In the right pane Actions menu, expand the Application section. Click on the Find… option.
   
7. In the text field, type Wininit and click on Find Next to look for the CHKDSK scan log.
   
8. View the results of the CHKDSK scan in the General tab.

7. Run diagnostics from BIOS/ UEFI

You can find out more about BIOS/ UEFI and how to access them on Windows 10 to get started with the hardware diagnostics.

1. Access the native or custom manufacturer BIOS/ UEFI on Windows 10.
   
2. Locate the Diagnostics or any other similar option and start the hardware diagnostics tests.
3. Follow any prompts that may show up accordingly.

BIOS/ UEFI is not as readily accessible as some of the other options on this list but is extremely useful in performing hardware diagnostics nonetheless. They are also the only option available for hardware diagnostics in case the PC fails to boot Windows.

BIOS/ UEFI layouts are not the same for everyone. Therefore, depending on the BIOS/ UEFI, you may have to explore a bit to find the Diagnostics section. It’s usually found in the Advanced section. If you don’t want to deal with BIOS/ UEFI, follow the next solution.

How often should I perform the hardware diagnostics process?

Hardware diagnostics is an essential part of maintaining your PC in general. However, given a PC’s performance, it may or may not be necessary.

If the PC is performing smoothly and you don’t find yourself running into errors, system crashes, or system freezing then you can safely perform a hardware diagnostics scan every 3-6 months.

But, if you do find yourself running into any or all of the above-mentioned issues, then you must perform a hardware diagnostics scan regularly.

A regular hardware diagnostics checkup will keep you updated on the performance of your hardware, automatically fix any issues if possible, and notify you about potential component replacements.

Moreover, you might want to use PC maintenance software in order to help your computer perform optimally all the time.
