Free Computer Diagnostic Software

[Pamala]

Ifyou've ever opened up your computer, you know there is a lot of hardware in there, and it's all a potential point of failure. Certain pieces of hardware are more prone to failure than others, but nothing lasts forever.

Did you note that CPUs are at the bottom of the list? CPUs can die, but they'll often be the last PC part to do so, and it's often caused by another issue, like power problems, overheating, or otherwise. Of all your PC hardware components, the CPU is the least likely part to have an issue, especially if you install it and then leave it alone (occasional thermal paste reapplications aside).

But no matter the hardware, the best way to avoid being caught out is to perform regular hardware diagnostic tests on your computer, and there are many ways to run hardware tests on Windows 10 and 11.

That's the easiest way to use the Windows Performance Monitor, but if you want more data, you'll find live performance graphs in Monitoring Tools > Performance Monitor and customizable data sets in Data Collector Sets > User Defined.

There are lots of warning signs when your RAM is close to failing. They include worsening performance, frequent crashes, video cards failing to load on boot, corrupted data files, and incorrect RAM information in the Windows System app.

If you're wondering how to run a memory test on the RAM, you need to use the Windows Memory Diagnostic tool. It works by writing to, then reading, your computer's RAM. Differing values signal faulty hardware.

MemTest86+ is well-established as the best tool to test your RAM on Windows. It's more powerful than Microsoft's Windows Memory Diagnostic tool and is free and open source. Furthermore, unlike the Windows tool, MemTest86+ also has a full-featured graphical interface.

Memtest86+ uses two RAM testing algorithms and supports DDR5, DDR4, DDR3, and DDR2 RAM. You boot it directly from a USB flash drive or a CD, and Microsoft has signed the app's code for Secure Boot compatibility.

The app's key feature is the "Self-Monitoring, Analysis, and Reporting Technology" (SMART) test. It provides data about several aspects of your drives, including the read error rate, a count of reallocated sectors, the spin-up time, and a whole lot more.

CrystalDiskInfo also includes advanced power and audio management tools for hard drives and SSDs. You can also configure CrystalDiskInfo to provide live alerts if drives become too hot or suffer from other failures. You have to keep CrystalDiskInfo running in the background to receive temperature alerts, but it's really not a problem as it requires very little processing power or system memory.

HWiNFO is way ahead of the hardware testing pack regarding the amount of information provided. But once you get up to speed with its extensive range of data, you'll appreciate it as one of the best computer diagnostic test apps out there.

From a hardware test standpoint, we are most interested in the app's system health monitoring features. They provide detailed real-time reports and graphs about your machine's CPUs, GPUs, mainboards, drives, and peripherals. Double-click any of the sections in the left-hand panel to open a new window filled with data specific to that hardware.

We've written about several tools that'll help you test the health of your laptop battery, but the best option for Windows users is the built-in tool, powercfg. The powerful command generates a precise report on your battery status and history, showing you its capacity and more.

The first part of the battery report details your hardware, current battery status, total capacity, and current capacity, which is all great information. If you scroll down, you'll find more information on charging status, periods, and more.

Another way to diagnose faulty hardware on a Windows system is with a Linux Live CD or USB. There are several rescue and recovery disks for Windows, but two useful distros for diagnosing faulty Windows hardware are PartedMagic and the Ultimate Boot CD.

PartedMagic is a paid tool but features several useful tools for benchmarking and checking your hardware, not to mention its disk partitioning, closing, rescue, and erasing tools, whereas the Ultimate Boot CD is completely free and also features numerous Windows hardware checking tools, testing and analytics options, plus fixes for common issues. As of Ultimate Boot CD version 5, the rescue disk also includes a version of PartedMagic (for partitioning and managing hard drives), so it's a very handy tool to keep around.

The Student Diagnostic Center (SDC) is staffed by IT student technicians and is supervised by IT user support staff. The SDC provides computer support services to Hampshire students having problems with their computer software and simple hardware problems. This service is available to Hampshire students free of charge.

Do I need an appointment?

While you don't need an appointment, we recommend scheduling online ahead of time. This helps us ensure that we can get to your computer as soon as possible and limits your wait time.

How Long Does the Comprehensive Computer Diagnostic Process Take?

The in-depth process usually takes about 1-2 hours, but this can vary depending on the severity of the issue and the type of computer being serviced.

What If I Am Under the Manufacturer's Warranty?

The Comprehensive Diagnostic fee is waived if you are still under warranty. Most warranty repairs can even be done in-house, and we will never do any work that voids your warranty.

What Happens if I Decide Not to Fix My Computer or My Computer is Beyond Repair?

If you decide not to fix your computer for any reason, there are no additional costs outside of the diagnostic fee. We will simply give you back your computer. However, we strongly recommend getting your computer fixed as soon as possible to avoid further damage. If your computer is beyond repair, we will let you know and provide options such as responsibly recycling the machine (with your written authorization), transferring your data to an external device or new computer, or returning your computer back to you.

Will You Ever Do Any Work Before I Approve the Repairs?

No, we will never do any work on your computer without your permission. We know that it's a big decision to get your computer repaired, and we want you to be confident in our services. That's why we'll always update you throughout the process and give you multiple options before moving forward with repairs.

What Certification do Your Technicians Have?

Our A+ certified techs undergo an extensive training and are experts in the field. They also have manufacturer-specific certifications from Apple, Dell, HP, Lenovo, and Microsoft.

I am planning to change my HDD with an M.2 SSD and I don't want to clone the previous OS installtion (along with the installed program) rather I just want to start with a clean installation as the previous installation (on HDD) has too much of data to clone (which would make the 256 gb ssd low on space) and it's the same case with the OEM's recovery discs and I am not gonna install Windows 10 with any of the methods.

What I want to know is - after installing Windows 10 on the SSD how could I get the "HP PC Hardware Diagnostic UEFI " that can be used to diagnos hardware before booting to Windows (which can be accessed by pressing F2 from the BIOS system startup menu), beacause when I would select this option after removing the HDD all the options to diagnos hardware would disapper making me believe that the files might be stored on the HDD.

Also currently I am usign the HDD and this option is still accesable from the BIOS (but when HDD is connected). Could any body tell me which of these partition stores the tool for "HP PC Hardware Diagnostic UEFI". (images in the link below)

Even after you replace the hard drive, you should still be able to access hardware diagnostics. In the case for any reason if you are unable to access it you can always download and install it from the link you have posted.

Also, let me completely describe what happened after I removed the HDD. I was able to access the HP hardware Diagnostic tool, but it didn't provide many options for testing hardware components (there were only 2 of them, i.e. memory check and Drive check). Wait this could be more descriptive if I would post images for the same.

I wanted to test something in Diagnostic startup mode. For some reason upon reboot, my PC showed my account picture with an error saying "Something happened and you PIN isn't available. Click to set up you PIN again." When I click on Set up my PIN, there is a pause, then I get the same message again. When I click on it again, I often get a dialog window saying "Search for app in the store" but if I choose yes, nothing happens.

I didn't try the other answer because it seemed super risky to move .exe files in System32 around, but I found another solution that only involves disabling the "pin-only" sign-on via RegEdit in Windows Recovery mode. This is I think a much less risky solution (and worked for me). Full credit to ramava on LTT for figuring this out. I'm pasting that answer below verbatim in case the link above breaks eventually:

This happened to me last night and I want to document it here so thathopefully someone else won't have to spend 3 hours trying to fix itthrough trial and error, or worse, have to "Reset my PC" or reinstall,which I was very close to doing before I solved it. Then later, Irecreated the problem on a virtual machine of a fresh Windows 10install to see which thing I did actually fixed it and discoveredanother potential problem that people may encounter. This may notsolve the problem completely if it was originally caused by somethingdifferent than my problem, but hopefully it'll be a good head startfor those people.
