If you use a Windows computer daily, sooner or later you'll find yourself needing to Check your PC specificationsTo install a game, check if a program will run smoothly, diagnose a problem, or decide whether it's worth replacing your computer or upgrading it piece by piece. While it may sound technical, Windows includes a lot of simple (and more advanced) tools that show you all this information without you having to be an expert.
In this complete guide you will learn how to see the System specifications from Windows Settings and also with other methods: Control Panel, Command Prompt, diagnostic tools such as DirectX or System Information, Performance Monitor, BIOS, Task Manager, and various third-party utilities. If you want to delve deeper into performance analysis and testing, see our complete diagnostic and performance guideFurthermore, you'll see why it's so important to know your PC's hardware well and in what situations it will get you out of more than one tight spot.
Which hardware specifications are really important
Although Windows can show you a huge amount of data, in everyday use what's most relevant is a small group of Key equipment specifications These factors determine its performance and compatibility with programs and games. These are the elements that need to be monitored:
- Pprocessor or CPUThe computer's "brain". Many programs require a minimum CPU power, so it's a good idea to know what model you have and what speed it runs at, especially if you notice that your PC gets hotter than usual or is strained when you edit video, play games, or use many applications at the same time.
- graphics card or GPUThis component handles everything you see on screen and is crucial for gaming, video editing, 3D design, and any demanding graphics task. Just like the CPU, an overloaded GPU can... trigger the equipment's temperature and cause stuttering, graphical artifacts, or even blackouts.
- RAMIt's responsible for handling all the tasks you have open simultaneously. The more RAM you have, the more applications you can run without the system lagging, but if you're running low on memory, you'll notice freezes, slow window switching, and longer loading times.
- MotherboardIts physical characteristics set very clear limits: number of RAM slots, compatible processor types, number of M.2 or SATA ports, etc. If you want to upgrade your PC, it's vital to know what your motherboard allows and what it doesn't.
- Type of storage and available space (HDD or SSD, total and free capacity) is also key. Not only for installing programs and saving files, but because an SSD can make a huge difference in boot and application loading speed compared to a traditional mechanical hard drive.
Why it's worth knowing your PC's specifications
Knowing what's inside your computer isn't just a technical curiosity. Understanding the system specifications It has practical advantages in many different situations, from technical support to gaming.
When you want replace components instead of buying a new PCKnowing the hardware well allows you to get the most out of an older machine and keep going hardware buying tipsIf you notice your computer is lacking in power, you can consider whether it's worth upgrading the RAM, switching to an SSD, changing the graphics card, or even installing a more powerful CPU if the motherboard supports it, thus extending the lifespan of the system.
It is also very useful when it comes to install heavy applications or modern gamesEvery serious program and every new title lists minimum and recommended system requirements. If you know what processor, how much RAM, what graphics card, and what operating system you have, you can avoid unnecessary purchases and headaches with games that won't start or programs that run sluggishly.
Another clear advantage is that it helps you understand the actual performance of your computerCurrent software and new operating system versions are increasingly demanding on CPUs, GPUs, RAM, and storage. If you know your computer well, you'll understand what kind of tasks it can handle smoothly and where it starts to struggle. Furthermore, knowing the location of your components allows you to troubleshoot problems. better identify the origin of the breakdowns.
Of course, all of this also applies if you want Sell your computer or buy a new one.When selling, View PC specifications —CPU, RAM, GPU, disk type and size, and Windows version— gives you confidence and allows you to better adjust the price. When buying, comparing it to your current computer helps you avoid falling short… or paying more for power you'll never use.
How to view specifications from Windows Settings
One of the most direct ways to check information about your PC is to use the Configuring WindowsIt is available in both Windows 10 and Windows 11. It is a native, simple, and quite secure tool for any user, although it does not show absolutely all the technical details.
In Windows 10 and Windows 11 the process is similar: open the Menu Start and go to Settings (the gear icon). Within the window that opens, go to the section System, which is where the main options related to hardware and display are concentrated.
In the left-hand menu, you'll need to scroll to the bottom to find the section you're interested in. In Windows 10, it's called "About", while in Windows 11 it appears under the name of "Information"It doesn't matter what it's called, because the function is the same: to show a summary of your device and Windows installation.
Within that section you will see, on one hand, the “Device specifications”with data such as the model and name of the device, the processor, the amount of installed RAM, the system type (32 or 64 bits), and some device identifiers. On the other hand, you will find the “Windows Specifications”with the operating system edition, version, build, and approximate installation date.
This method is perfect for a quick consultation of CPU, RAM and Windows versionHowever, it has its drawbacks: you won't find the graphics card model, hard drive or SSD details, or all the fine-tuning information about the motherboard or peripherals. Even so, it's an essential first step before moving on to more comprehensive tools.
Control Panel and other basic options in Windows
Although Windows Settings has taken center stage, the classic Control panel It's still there and remains one of the most well-known ways to view basic PC features, especially in Windows 7 and on computers that have been updated over the years.
To use this method in Windows 10, you can open the taskbar search bar and type “Control Panel”. When it opens, go to the section "Security system" and, within it, click on "System"You will see a window with information about the processor, RAM, operating system type, and some manufacturer support details.
In Windows 7, access is very similar. You can right-click on “Equipment” and click on “Properties” to open that same tab. Although the information isn't particularly extensive, it's usually enough to know at a glance what processor you have, how much RAM is installed, and what version of Windows you're using.
If you want to delve a little deeper from that screen, you have the option to enter the Device administratorThe link usually appears on the left side. From there, you can expand categories such as display adapters, disk drives, sound controllers, etc., to see the exact name of each component that Windows has detected.
Another basic, though somewhat more technical, way is to use the window Run and the Command PromptPressing the Windows + R key combination opens Run, where you can type cmd To launch the classic console. Inside, if you type the command systeminfo And if you press Enter, the system will generate a fairly detailed list of information about the hardware and operating system.
Advanced Windows diagnostic tools
When basic options fall short, Windows offers several internal diagnostic tools that allow you to know your PC in much more detail.
One of the most useful is the DirectX Diagnostic Tool, known as DxDiag. To open it, simply press Windows + R again, type dxDiag and press Enter. After a few seconds, a window will appear with several tabs: System, Display, Sound, and Input.
In the System You'll see a general summary of the machine: Windows version, computer manufacturer, model, BIOS type, processor, amount of memory, etc. In the tab Screen You'll get details about the graphics card, video memory, manufacturer, and driver type—very useful information to check if you meet a game's graphics requirements or if you need to update your drivers.
If you want an even broader view, you have the tool System informationwhich opens by typing “System Information” or “msinfo32” in the Windows search bar. It is probably the most comprehensive built-in utility for View all your PC specificationsalthough its interface is quite dense.
In section “System Summary” You'll see information about the processor, physical memory, motherboard, BIOS version, and general settings. Below, by expanding the categories... “Components”, “Hardware resources” y “Software environment”You'll find everything from details about the sound card and network to loaded drivers and programs that start with Windows.
Check CPU, RAM, GPU, motherboard and storage in detail
Beyond the general summary, what you often need is to examine a specific component closely: processor, graphics card, memory, disk or motherboard.
For CPUYou can start from Settings or Control Panel to see the processor name and its reference speed. Alternatively, you can type "CPU" in the search bar and open the link to “View processor information”, which usually shows the full model and the declared base frequency in GHz.
If what you're interested in is reviewing the amount of RAMGo back to Settings > System > About and check the "Installed RAM" section. You can also check this by going to the System Information panel or through the... Task Manager, on the Performance tabwhere you'll see not only the total amount, but also the type, speed, and real-time usage.
For graphic design or GPUThe most direct way is to open the Device administrator From the Start menu, expand "Display adapters". The full name of the graphics card will be listed there.
As to storageYou can open System Information and go to Components > Storage > Disks. There you can check the drive type (SSD or HDD), the total size, the serial number, and other interesting information about each connected disk.
La motherboardThis often overlooked information can also be found in System Information. The summary includes the motherboard manufacturer and specific model, essential if you want to find manuals, BIOS updates, or check which processors and RAM modules it supports before considering an upgrade.
RAM memory diagnostics and performance monitor
In addition to displaying static data, Windows includes utilities for test the status and performance of your hardwareOne of the most interesting is the Windows Memory Diagnostic tool, designed to detect possible failures in RAM modules.
To launch it, you can again use Windows + R to open Run, type mjed (in some texts it appears as mdschedk) and press Enter. The system will offer to restart your PC and run the diagnostic. It is important to save everything you have open, because The process requires restarting the computer. and you won't be able to use it during the trial.
Another very useful tool is the Performance and Resource Monitorwhich not only measures real-time usage, but also generates a complete system status reportTo open it with a quick diagnostic, use Run (Win + R) again, type perfmon / report and hit Enter.
After approximately one minute of data collection, a report is generated, structured into several sections: diagnostic results, software configuration, hardware configuration, CPU, network, disk, and memory sections, and general statistics. Within "Diagnostic Results," you will see any warnings, tests performed, and resource usage summaries.
In the sections dedicated to CPU, network, disk and memory You can identify spikes in excessive usage, services that are drastically impacting performance, abnormal disk response times, or processes that are consuming a lot of RAM. It's an invaluable tool for uncovering bottlenecks and performance issues that are easily missed.
View hardware from the BIOS and Task Manager
When you need an even greater level of detail, or when Windows doesn't start correctly, another option is to resort to the BIOS or UEFI of the computerFrom there you can check some of the installed hardware and some operating parameters.
The first is access BIOSOnce inside, the main screen usually displays the motherboard model and manufacturer, the type of processor, the amount of memory, the BIOS version and, in many cases, information about clock speed, temperatures, fans and some advanced features of RAM and CPU.
If you want a quick overview of resource usage without leaving Windows, the Task Manager It's your ally. There are different tabs:
- UnlimitedThere you will see real-time graphs and data of CPU, memory, each disk, network adapter (WiFi or Ethernet) and GPU.
- CPUThis displays the processor model, its current speed, the percentage of use, the active processes and subprocesses, and the time the system has been powered on, among other data.
- Memory. It indicates the total amount of RAM, current usage, available memory, cached memory, speed, module type, or even how many physical slots are occupied.
- DiscHere you can see if it's an HDD or SSD, the capacity, uptime, and real-time read and write speeds.
- RedThe Wi-Fi or Ethernet graph displays incoming and outgoing traffic, adapter name, connection type, wireless signal strength, and other useful values.
- GPUThis section displays the card name, its use, video memory, the installed driver version, and DirectX compatibility—key data for gaming and graphics tasks.
Third-party applications for analyzing hardware
If the built-in Windows tools fall short or prove cumbersome, there are other options available. specialized external utilities These show you system information much more clearly and, in many cases, include extra monitoring and performance testing features. These are the most effective:
- CPU-ZA free program that has become the de facto standard for viewing detailed information about the processor, motherboard, memory, and other key components. It organizes information into tabs and displays real-time frequencies, memory type, latencies, and even basic CPU performance tests.
- SpeccyIt stands out for its simplicity and for presenting PC specifications in a very visual way. It shows you the processor brand and model, the amount of RAM, the operating system, the graphics card, the motherboard, the hard drives, and much more, including real-time temperatures of the CPU and other components.
- AIDA64 Extreme. It offers a vast array of information, stability tests, benchmarks, and sensor monitoring. It has a limited free version and a paid version with full features. It can display voltages, fan speeds, exact temperatures, and other data.
- HWInfo. It combines comprehensive reports with a very complete real-time monitoring system. It allows you to view CPU, GPU, RAM, disk, and operating system specifications on a single screen, as well as record data for later analysis.
- CrystalDiskInfo It reads the SMART information from your drives, both internal and external, and displays it clearly. This allows you to detect reallocated sectors, abnormal temperatures, or health warnings that indicate it's a good time to replace the drive before data loss occurs.
With all of the above in mind, having a good mental map of your CPU, GPU, RAM, motherboard, disks, and Windows version becomes a fundamental tool for choosing what to install, when to upgrade components, how to solve performance errors, and even what price to ask for your PC when you decide to sell it.
