Top 5 PC Hardware Diagnostic Tools

  • Owning a good PC diagnostic tool can make a big difference in our times.
  • Keeping up to date with various outages is even more important if you are storing sensitive information.
  • A Windows 10 PC hardware diagnostic software will monitor the various components to identify any faults that could lead to system failure.
  • Your RAM is a good indicator of possible abnormalities, but you need more than a Windows 10 memory diagnostic.

Windows 10 has an intuitive user interface due to which it has quickly become the most popular operating system. But it is far from perfect.

Just like in other operating systems, there are times when you will face issues like blue screen of death, system crashes (BSOD), latency issues, etc.

Most of these failures are triggered by hardware-related issues.

Fortunately, various computer hardware diagnostic tools can help you out instantly. 

In this article, we have listed the best PC diagnostic tools to deal with the most common errors present in different components of your system.

So, instead of hiring an expert to fix the problem for you, we recommend that you try these tools first.

Which tool to diagnose a computer problem?

AIDA64 Extreme

AIDA64 is a hardware monitoring software for Windows 10 which targets home users, enterprise engineers and enterprises.

The tool offers detailed information on more than 185,000 hardware devices.

Thus, it helps to monitor hardware details at all times, even when watching a movie on full screen or while playing a game.

AIDA64 Extreme measures your system's performance with various calculations that compare it to other systems, accurately, or to beat the user's own scores when overclocking.

The tool also allows users to manage the business remotely and monitor changes to software and hardware.

Windows Memory Diagnostic

Also known as mdsched.exe, the Windows Memory Diagnostic Tool runs comprehensive tests on your computer's memory.

Its purpose is to look for any errors that may stifle proper operation.

This tool tests your memory for defects and displays the test results so you can take action. 

Since it's a built-in diagnostic tool, you don't need third-party software. To run it, please 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.

Either way, the Memory Diagnostic Tool will run tests on your machine and notify you of any faults in memory, including RAM.


If you notice spots on your screen that are not caused by dust, then you may be dealing with stuck pixels. And those that can get really inconvenient.

A stuck pixel is a visible point of colour that does not change when neighbouring pixels change. These pixels become very visible when the screen goes black.

If the stuck pixels are not the result of screen defects, JScreenFix can fix the problem. 

It works by rinsing the affected area with hundreds of different colours every minute. In this way, it only takes a few minutes to peel off the pixels.


Most modern computers come with an  SSD drive which has its own advantages but is also known to stop working without warning.

But if you want to know if your SSD or hard drive is in good condition, the tool to use is none other than CrystalDiskInfo. 

This tool performs a comprehensive scan of the status of your data drives, including USB drives, SSDs, and HDDs.

It calculates overall health and gives you details about error rates, uptime, boot time, and temperature.

Intel Processor Diagnostic Tool

However, they are not immortal and can develop abnormalities, although this is usually the result of an electrical surge or overheating.

Fortunately, the Intel Processor Diagnostic Tool can help you troubleshoot any issues caused by faulty processors.

The tool performs various stress tests on the processor, tests specific processor features, checks the operating efficiency of processors, and verifies brand identification.

Then the tool displays the test results. If any of the results fail to meet working standards, the tool will indicate which parameters failed.

The tool can be downloaded from Intel's website. However, be sure to download the correct version for your machine, 32 or 64 bit.

Chances are that the problems with your PC are caused by faulty hardware.

Having the knowledge of diagnostic tools can save you time and the cost of hiring an expert.

There are many diagnostic tools you can use to troubleshoot hardware issues. Since we couldn't cover them all in one batch, we hope you find the ones featured above useful.
