Microsoft designed Windows 10 and Windows 11 with the efficiency of its users in mind, making it simple to handle all parts of your system while also making it attractive.

However, Windows still has room for improvement when it comes to specialized hardware monitoring and diagnostic capabilities.

Because issues like BSOD, system crashes, and sluggish interface difficulties are likely to occur at some point, keeping track of all elements of your system’s hardware may be beneficial.

The majority of these problems are hardware-related and, if not solved, may result in a horrific encounter.

The data collected with a system diagnostic tool may be utilized as a preventative measure as well as to address any existing problems.

Even while Windows provides the Windows Memory Diagnostic Tool, it typically just performs a few things like delete unnecessary files and make small adjustments, so selecting a decent diagnostic tool is critical.

In contrast to Windows 10, the new version of troubleshooting software on Windows 11 has improved, but it still lacks the full range of functions and information that a decent third-party program may provide.

What is the purpose of hardware diagnostic software?

Obtaining current information on the status of your hardware may make a significant impact over time, increasing usability while also ensuring that your gear lasts longer.

Lacking knowledge of how your PC’s hardware responds to the everyday activities you subject it to may result in system crashes, OS difficulties, and even application troubles.

A hardware diagnostic tool guarantees that various system parameters are in the optimum range, allowing you to get the most out of your equipment.

Here are some of the things a decent hardware diagnostic tool can do for your system:

  • Provides comprehensive information about all of the hardware on your computer.
  • Contains sensor management tools that display real-time temperature and workload data.
  • Provides up-to-date information on the amount of virtual memory available.
  • Provides helpful benchmarking tools for comparing the hardware in your system.

It’s possible that your PC has memory problems if it reboots or doesn’t boot at all. This is where Windows Memory Diagnostic, one of the finest free memory testing applications currently available, comes in.

You should know right away that it is simple enough for anybody to profit from, and the outcomes will not disappoint you.

The Windows Memory Diagnostic Tool, often known as mdsched.exe, performs extensive checks on your computer’s memory, looking for any errors that may prevent it from operating properly.

To be more specific, it examines your memory for flaws and shows the findings so you can act.

Keep in mind, however, that you do not need to intervene at this stage since the verification is entirely automated. The real memory test sets will continue to run until the computer is turned off.

Because this is one of the built-in diagnostic tools, you won’t need to use a third-party tool to obtain the data you want. If you’ve already decided on a third-party program, do a second test using Windows Memory Diagnostic just to be sure.

Follow the instructions below to run it:

  1. To launch the Run dialog box, press the Win + R keys together.
  2. To launch it, type mdsched.exe and click Enter.
  3. You may either restart the computer and check for issues or wait until the next time you restart it to look for problems.

In any scenario, the Memory Diagnostic Tool will perform checks on your computer and warn you of any memory faults, such as RAM, that may result in a system failure.

Is it safe to use hardware diagnostic tools?

We can’t apply this concept too broadly since not all hardware diagnostic tools are created equal. According to our findings, hackers and other third parties have exploited the appearance of a diagnostic application to sneak malware and bloatware onto computers over time.

This means that each choice about whether or not to install the program will have to be handled individually.

It is usually advised that you download software exclusively from approved sites to make the procedure easier.

As you would expect, any program you download from our site does not expose your system to any potential hacking attempts, so you can feel safe with this concept.


There’s a high probability your computer’s problem is defective hardware, and there’s a program you can use to repair it in the least amount of time.

Knowing these diagnostic programs may help you save time and money by avoiding the need to hire a professional.

There are numerous diagnostic tools available for fixing hardware issues, and although we couldn’t cover them all here, we hope you find the tools listed above helpful.

You should save this page because you may need to return to it if you encounter the same or a similar issue in the future.
