How to check your PC’s components in Windows 10

By September 10, 2020September 10th, 2021No Comments

Now and then, you might need to know what components your PC has installed. In particular, you might need to know specifics of the central processing unit (aka the CPU or processor), the graphics processing unit (aka the GPU or graphics card), the random access memory (RAM), or storage (hard drives or solid-state drives).

Some examples of when this information would come in handy include technical support calls, software requirements and recommendations, and assessing whether your PC is fast and well-equipped enough for your overall needs. Regardless of the reason, there are several PC part checker tools built into Windows 10 and available from 3rd-party developers that can tell you everything you need to know.

System Information

The first place you can look for information on your PC’s configuration is Settings > System > About. The easiest way to get there is to right-click on the Windows icon and select “System” from the menu.


This is how to check PC parts according to Microsoft. A window will pop up giving you a variety of useful information, including your PC’s name, the CPU it uses, the installed RAM, and information on the version of Windows 10 that’s installed. This information can help you diagnose problems and understand the essential aspects of your PC’s performance.


Settings System info

If you scroll through this page, you’ll find opportunities to change your Windows 10 product key, upgrade your edition of Windows 10, and access a different view of the same system information.

Device Manager

If you want information on more components along with the ability to make changes to installed component drivers, then you can open Device Manager from the Control Panel. You can get there quickly by right-clicking on the Windows icon and selecting “Device Manager” from the menu.

Right-click Device Manager popup


More than just a PC part checker, it allows you to expand various categories, and gain access to a great deal of useful information. You can see a list of the storage devices installed in your PC, the display adapters, the monitors, the network adapters, the processors, and much more. Also, if you have any problems with a given component, it will show up here.


Device Manager info


If you double-click on any of the installed devices, then you can get additional technical details, including the opportunity to update drivers and read specific error information. Problems stemming from synching multiple Windows 10 devices require other solutions.


Device Properties popup

Task Manager

Perhaps you’re more interested in how your various components are performing. For that, you can open the Task Manager and select the Performance tab. There, you can get information on CPU, RAM, storage, and GPU utilization.

Task Manager GPU

Task Manager RAM


This information can help diagnose problems, such as a CPU that’s running too hard and causing extra heat and fan noise. Check out the Processes tab for information on which applications are using the CPU, RAM, storage, and GPU – that, too, can help diagnose system problems.


Task Manager Processes info


Another tool that’s accessible via the Task Manager is the Resource Monitor. Click on the link at the bottom of the Performance tab to access more in-depth information on CPU, RAM, disk, and network utilization.

This tool will show you how many cores your CPU has and how each is being used. Note that in a multithreaded CPU, you’ll see how many threads your processor is capable of running rather than the number of physical cores.

Also helpful is the available information on how your RAM is utilized and how hard your various storage devices are working. Finally, you can see how much network bandwidth your PC is using, which can help you understand any network performance issues you’re experiencing.

System Information

The final Windows 10 solution to the, “how to check PC parts” question is the System Information utility. The easiest way to access it is to type “System Information” into the search box, and then select the app when it pops up.

System Information provides perhaps the most information of all of the Windows 10 tools, including a considerable amount of data as a system summary. Here, you can see more information about your Windows 10 installation and your PC, including the system model if it’s available, and specifics on your RAM and its configuration.

System Information info


Expand the “Hardware Resources” category, and you can access information on several system components. One particularly valuable bit of information is on your storage devices, which is broken out by device type.

You can also expand the Software Environment category to find out more about your Windows 10 installation. That’s beyond the scope of this guide, but it’s valuable information as well for diagnosing problems.

It’s also important to have your notifications dialed in so you don’t get desensitized to junk notifications and miss the ones that really matter.

3rd-party Applications

In addition to the resources built into Windows 10, there are many 3rd-party PC part checkers that you can install that will give you even more detail about your system configuration. For example, HWiNFO64 is a free application that provides you with more information about your PC than you’ll likely ever need, unless you’re really into the technical details of how your PC is running.

The HWiNFO64 System Summary screen shows you various details about your CPU, your GPU, your RAM, and your storage devices. This screen includes a variety of performance metrics that can help determine if you have the right components installed for your needs.



You can close the System Summary screen and access additional information about your PC components.

If you click on a component, such as the GPU, you can get even more detailed information. In the case of the GPU, for example, you can find out what bus it’s connected through (PCIe), how much video RAM is installed (4095 megabytes), and what the driver version is (

You can also use HWiNFO64 to track how your components are performing, and how much heat they’re generating. That, too, is beyond the scope of this guide, but if you need to solve issues with heat and fan noise, as well as performance problems, then this information can be invaluable.

HWiNFO64 is just one system information utility that’s available for Windows 10. Search, and you’ll find hundreds. Just be sure to exercise caution when installing any free apps, because they can sometimes come with adware and other unwanted add-ons that install alongside the utility.

Everything you need to know

Between these various utilities, you can find out just about everything you need to know about the components installed inside your PC. Whether it’s your CPU, GPU, RAM, or storage, you can find the brand, configuration, driver level, and more with just the tools built into Windows 10. And if you want to branch out from there, many 3rd-party applications stand ready to lend a hand.
