Microsoft has created Windows 10 and Windows 11 with users’ efficiency in mind, making it easy to manage all aspects of your system while making it look good at the same time.

That being said, when it comes to specific hardware monitoring and diagnostic tools, Windows still has things to improve.

Because errors like BSOD, system crashes, and lagging interface problems are bound to happen at least once in a while, monitoring all aspects of your system’s hardware can provide you with useful information.

Most of these issues are hardware-related consequences and may give you a gruesome experience if not addressed.

The information obtained with a system diagnostic tool can be used as a preemptive measure, and also to resolve any issues that already appeared.

Even though Windows offers the Windows Memory Diagnostic Tool, it usually doesn’t do much other than clear up useless files and other minor fixes, so the importance of choosing a good diagnostic tool can make a big difference.

In comparison with Windows 10, the updated version of troubleshooting software has been improved on Windows 11 but still doesn’t offer the entire range of features or the amount of information a good third-party software can.

What does a hardware diagnostic software do?

Getting updated information about the state of your hardware can make a huge difference across time, improving usability, and at the same time ensuring that your hardware lasts longer.

Not having any idea about how your PC’s hardware is dealing with the daily tasks that you expose it to can end up causing system crashes, issues with your OS, and even problems with your applications.

A hardware diagnostic tool ensures you that different parameters of your system are in the optimal zone, and thus optimize the way you can use your device.

Here is what a good hardware diagnostic tool can help your system with:

  • Offers detailed information about all the hardware installed on your PC
  • Contains sensor managing tools that show you exact temperature and workload information in real-time
  • Presents constantly updated information about the available virtual memory
  • Provides useful benchmark tools to compare your system’s hardware

Memory Diagnostic Tool

If your PC randomly reboots or doesn’t boot at all, it may have memory-related issues. This is where Windows Memory Diagnostic steps in, as one of the best free memory testing programs available at the moment.

You should know from the start that it is easy enough for anyone to benefit from and you won’t be disappointed by the results.

Also known as mdsched.exe, the Windows Memory Diagnostic Tool runs comprehensive tests on your computer’s memory checking for any error that may stifle proper functioning.

To be more precise, it tests memory for defects and displays the results so that you can take action.

However, keep in mind that no intervention is required on your part at this point since the verification is completely automatic. As for the actual memory test sets, they will continue to repeat until the PC is powered off.

This is one of the inbuilt diagnostic tools so you don’t need a third-party tool to get the desired results. If you already have a third-party tool in mind you should always test a second time with Windows Memory Diagnostic just to be sure.

To run it, follow the steps below:

  1. Press the Win + R keys to open the Run dialogue box.
  2. Type mdsched.exe and press Enter to run it.
  3. Choose either to restart the computer and check for problems or to check for problems the next time you restart the computer.

In either case, the Memory Diagnostic Tool will run tests on your machine and will notify you of any defects in the memory, including RAM that may cause a system failure.

Are hardware diagnostic tools safe?

We can’t generalize this idea too much, as not all hardware diagnostic tools are made the same. Our research has suggested that across time, hackers and other third parties have used the disguise of a diagnostic tool to pack in malware and bloatware.

This implies that every decision made in regards to installing or not installing the software will need to be processed separately.

To simplify the process, it is always recommended that you download software only from official sources.

As you might already assume, any software that you will download from our site doesn’t expose your system to any possible hacking attempt, so you can rest assured by this idea.


There is a good chance that the problem with your computer is faulty hardware and there is a tool that you can use to fix the issue in the shortest time possible.

Knowing these diagnostic programs might save you time and the cost of hiring an expert.

There are many diagnostic tools that you can use to fix hardware problems and since we could not cover all of them in one lot, we hope that you will find the above tools useful.
