The fastest way to check your PC specs on Windows is to open Task Manager (Ctrl+Shift+Esc), click the Performance tab, and read the CPU, Memory, Disk, and GPU entries, then confirm anything missing in Settings under System and About. For a full single report, press Win+R, type dxdiag or msinfo32, and press Enter.
You need to know your specs before buying a game, upgrading RAM, picking a graphics card, or asking for help in a support forum. This guide walks through the built-in Windows tools step by step, explains what each number means, and shows how to spot common surprises such as memory running below its rated speed. Menu names can shift slightly between Windows 10 and Windows 11 and between updates, so use the search box in Settings if a path looks different on your machine.
The quickest check: Settings and Task Manager
These two places answer most questions in under a minute and do not require installing anything.
Settings, System, About
- Right-click the Start button and choose Settings, or press Win+I.
- Open System, then scroll down to About.
- Under Device specifications you will see the processor name, installed RAM, system type (64-bit or 32-bit), and device name.
- Under Windows specifications you will see the edition and version, which matters for game and driver compatibility.
The processor line shows the model and base clock. It does not show how many cores it has, so use Task Manager for that.
Task Manager Performance tab
- Press Ctrl+Shift+Esc to open Task Manager. If it opens in a compact view, click More details.
- Select the Performance tab.
- Click CPU to see the model, cores, logical processors, and current speed.
- Click Memory to see total capacity, speed, and how many slots are used.
- Click Disk entries to see each drive’s model and whether it is an SSD or HDD, plus capacity.
- Click GPU entries to see the graphics card name, dedicated video memory, and driver details.
If you have both integrated and dedicated graphics, you will see two GPU entries. Your games should be using the dedicated one.
Reading each component correctly
CPU: model, cores, and threads
The model name tells you the family and generation. Cores are the physical processing units, and logical processors are the threads they can handle. Many modern chips show twice as many logical processors as cores. Look up the exact model on the maker’s site for the official specification sheet.
RAM: capacity, speed, and slots
Capacity is shown in gigabytes. Speed appears in megahertz or megatransfers per second depending on the Windows version. Slots used tells you whether you have room for upgrades. A very common surprise is memory running at a lower default speed than the package states, because the profile that unlocks the rated speed (called XMP on many boards or EXPO on others) must be turned on in the BIOS or UEFI.
GPU: model and video memory
Task Manager lists the graphics card name and dedicated GPU memory. Shared GPU memory refers to system RAM that the graphics system may borrow, and it is not the same as the video memory on the card itself. For the clearest information, the card name is what you search for to find the official spec page.
Storage: type and free space
Under Settings, System, Storage, you can see drive usage and open Advanced storage settings to find the disks and volumes. Task Manager shows whether a drive is an SSD or HDD. To tell NVMe from SATA, search the drive model name on the manufacturer’s site, since the label alone often does not say.
The full reports: DxDiag and System Information
When you need a single page to share or screenshot, these built-in tools collect everything.
DirectX Diagnostic Tool
- Press Win+R, type dxdiag, and press Enter. Accept the prompt if Windows asks to check for signed drivers.
- On the System tab, read the processor, memory, and DirectX version.
- Open the Display tab to see the graphics card, driver version, and video memory. Check the tabs for each display or render device if you have more than one.
- Choose Save All Information to export a text file you can attach to a support request.
System Information
- Press Win+R, type msinfo32, and press Enter.
- In System Summary, find the motherboard maker and model (listed as BaseBoard), BIOS version and date, and total installed memory.
- Expand Components, then Display or Storage for more detail.
The motherboard and BIOS lines are useful before upgrading a processor, since support depends on both the board and its firmware version.
Command-line options for power users
If you prefer typing to clicking, Windows includes text commands that print the same information. They are handy for copying results into a support message.
System Information in Command Prompt
- Click Start, type cmd, and open Command Prompt.
- Type systeminfo and press Enter. It may take a few seconds to collect data.
- Read the processor, BIOS version, total physical memory, and operating system lines.
This output does not include the graphics card details in a friendly form, so use Task Manager or DxDiag for that.
PowerShell queries
PowerShell can list components through built-in management queries. For example, searching online for the Get-CimInstance command with Win32_VideoController or Win32_PhysicalMemory returns details like the video card name and memory module capacity and speed. Older commands based on wmic are being phased out in recent Windows versions, so prefer PowerShell if you are following a newer guide.
Reading the results safely
Copy only the lines you need when sharing results in a public forum. Serial numbers, product keys, and your computer name are not necessary for most help requests, so leave them out.
Optional third-party tools
Built-in tools do not show everything, such as exact memory timings or sensor temperatures. Free utilities from reputable developers, including CPU-Z, GPU-Z, and HWiNFO, can fill the gaps. Download only from the developer’s official website and check the publisher before running anything.
Checking your display and Windows settings
Specs are not only about the parts inside the case. Your display setup affects what you see, and a quick look can reveal a common mistake.
Refresh rate and resolution
Open Settings, System, Display, then Advanced display. Check the refresh rate listed for each monitor. A high refresh rate monitor often defaults to 60 hertz until you select its faster setting, and the same panel can look noticeably smoother after the change.
Windows version and updates
Under Settings, System, About, the Windows specifications show the edition and version. Some features, like newer graphics APIs and certain game options, depend on a current version, so keep Windows updated through Windows Update.
What to compare against
| What you found | Where to check it | What to compare it with |
|---|---|---|
| CPU model | Task Manager, Settings | Game minimum and recommended specifications |
| RAM capacity and speed | Task Manager, DxDiag | Rated speed on the memory kit and motherboard support |
| GPU model and VRAM | Task Manager, DxDiag | Target resolution and game requirements |
| Drive type and free space | Settings, Task Manager | Installation size plus update space |
| Motherboard and BIOS | System Information | CPU support list on the board maker’s site |
If something looks wrong, such as a missing memory stick, a drive that does not appear, or a graphics card listed as a basic display adapter, restart the PC first and check again. A basic display adapter name usually means the proper driver is not installed, so download the current driver from the graphics maker. If a component is still missing after a restart, power off, unplug, and reseat it carefully, or contact the manufacturer or seller.
Before you act on what you found
- Write down or screenshot your CPU, RAM, GPU, storage, and motherboard model.
- Check that the numbers match what you expected when you bought the PC.
- Confirm the monitor is running at its intended refresh rate in Settings, System, Display, Advanced display.
- If you plan to open the case, power down, unplug, discharge static by touching bare metal, and back up important files first.
Common Mistakes
- Reading shared GPU memory as if it were the card’s own video memory.
- Assuming RAM is running at its advertised speed without checking the BIOS profile.
- Trusting a store listing over what the system actually reports after a build or repair.
- Counting logical processors as physical cores.
- Downloading monitoring tools from unofficial mirror sites.
