Best Hardware Diagnostic Tools for Windows 10

Memory Diagnostic Tool


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. This tool tests your memory for defects and displays the test results so that you can take action. This is one of the inbuilt diagnostic tools so you don’t need a third party tool. To run it, follow the steps below:

Step 1: Press the ‘Win + R’ keys to open the Run dialogue box.

Step 2: Type ‘mdsched.exe’ and press Enter to run it.

Step 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 system failure.

If you notice some spots on your screen that are not caused by dust or stains, then your screen may have some stuck pixels which can be very annoying. A stuck pixel is a conspicuous dot of color that fails to change when the neighboring pixels change. Such pixels become very noticeable when the screen turns black. If the stuck pixels are not as a result of defects in the screen, then JScreenFix can fix the problem. It works by flushing the affected area with hundreds of different colors every minute. This way, it takes only some few minutes to unstick the pixels.

Most modern computers come with Solid State Drive (SSD) which has its own advantages but is also known to die without giving a warning. But if you want to know if your SSD or hard drive is in good condition, the tool to use is no other than CrystalDiskInfo. This tool performs a complete analysis of the state of your data drives including USB drives, SSDs, and HDDs. It calculates the overall health status and gives you details about error rates, uptime, spin-up time, and temperature. The program has a sibling called ‘CrystalDiskMark’ which you can also use to gauge how fast your data drives can read and write.

Intel Processor Diagnostic Tool


Of all the components in your computer, processors are the least likely to cause problems. However, they are not immortal and can die just like other components, though it’s usually as a result of an electrical surge or overheating. Thankfully, the Intel Processor Diagnostic tool can help you fix all issues caused by faulty processors. How does it work? The tool performs various stress tests on the processor, tests specific processor features, verifies the processors operating efficiency, and checks for brand identification.

The tool then displays the test results. If any of the tests results does not meet the standards for operating efficiency, the tool will display the tests that failed and you have to look into getting new processor. The tool can be downloaded from Intel’s website. However, make sure to download the right version for your machine, 32 or 64 bit.

Reliability Monitor


Reliability Monitor is a hidden gem in Windows that Microsoft needs to underscore its importance by shining more light on it. The tool tracks the history of your computer. Any time your computer hangs, an application crashes, or misbehaves in any way, the scenario is recorded in this tool. It also tracks other events such as when Windows Updates loads a new patch or when new software is installed.

The blue line gives an estimation of how stable your system is over time on a scale of 1-10. To access it, go to control panel, choose System and Security > security and maintenance > maintenance > view reliability history. If your system has been crashing a lot, this should be the best place to check as you will be able to check the error and look for the solution.

Windows System Troubleshooter

There is no better place to look for solutions to product’s problems than in the manufacturer’s site. Microsoft is aware of the bugs and other problems that plague their operating system, and because of that, the company launched their own troubleshooting tool called Microsoft Fix It Solution Center. Unfortunately, the tool is not available for Windows 10. However, Windows 10 users are not left without solutions as the Windows System Troubleshooter has the capability to solve most system problems from audio issues to corrupted programs and other hardware issues that affect performance efficiency.

The best part of using Windows system troubleshooter is that it doesn’t require prior installation of additional software.

This will show you the available options to fix the problem.
