The fastest way to see what's inside your computer

You can see your PC's core specifications in under a minute using the System Information tool built into Windows. Press the Windows key and R together, type msinfo32, and hit Enter. A window opens showing your processor, RAM, operating system version, and system type all in one place. This is the quickest route if you just need the basics.

If you want more detail—graphics card, storage drives, motherboard model—you'll need to check a few different places, since Windows spreads this information across multiple tools. The sections below walk you through each one and explain what you're looking at.

Key Takeaways

  • Open System Information by pressing Windows key + R, typing msinfo32, and pressing Enter to see processor, RAM, and OS version when ready.
  • Check your graphics card in Device Manager by right-clicking the Windows Start button, selecting Device Manager, and expanding Display adapters.
  • View storage drives and their capacity in File Explorer by right-clicking This PC and selecting Manage, then opening Disk Management.
  • Use the Settings app (Windows key + I) and navigate to System > About to see a summary of your device name, processor, RAM, and system type.
  • Third-party tools like CPU-Z and GPU-Z show detailed hardware information in a single window if you prefer not to dig through multiple Windows tools.

Check processor, RAM, and operating system in System Information

System Information is the official Windows tool for hardware details. Press Windows key + R, type msinfo32, and press Enter. The window that opens shows your processor name and speed under "Processor", your RAM amount under "Installed Physical Memory", and your Windows version under "OS Name".

The processor line tells you the brand (Intel or AMD), the generation, and the number of cores. For example, "Intel Core i7-12700K" means it's an Intel processor, 12th generation, model 700, with the K suffix indicating it's unlocked for overclocking. The RAM figure is the total amount available—if it says 16384 MB, that's 16 GB.

This tool also shows your system type (64-bit or 32-bit), which matters if you're installing software or checking compatibility. Most modern PCs run 64-bit, which can use more than 4 GB of RAM.

Find your graphics card in Device Manager

Your graphics card (GPU) is not shown in System Information. To find it, right-click the Windows Start button and select Device Manager. Look for the category called "Display adapters" and click the arrow next to it to expand the list.

You'll see your graphics card name there. If it says "NVIDIA GeForce RTX 3060" or "AMD Radeon RX 6700", that's your dedicated graphics card—a separate piece of hardware made for gaming and graphics work. If it says "Intel Iris Xe Graphics" or "AMD Radeon Graphics", that's integrated graphics built into your processor, which is slower but uses less power.

If you see two entries under Display adapters, one is usually your main card and the other is a backup or integrated option. Right-click the card name and select Properties to see the driver version and memory amount, though the memory figure shown here is often inaccurate for dedicated cards.

Check storage drives and capacity in Disk Management

To see how many storage drives you have and how much space each one holds, right-click the Windows Start button and select Device Manager. Scroll down to "Disk drives" and expand it. Each drive listed is a physical storage device in your PC.

For a clearer view of storage, open File Explorer, right-click This PC on the left sidebar, and select Manage. Click Disk Management in the left panel. You'll see each drive listed with its total capacity and how much space is used. A drive labeled "Disk 0" or "Disk 1" is a physical drive; partitions (labeled C:, D:, etc.) are sections of those drives.

The storage type—solid-state drive (SSD) or hard disk drive (HDD)—is not shown in Disk Management. SSDs are faster and more common in newer PCs; HDDs are slower but cheaper. You can usually tell by opening File Explorer, right-clicking your main drive (usually C:), selecting Properties, and looking at the speed listed, though this method is not always reliable. Third-party tools (covered below) show storage type more clearly.

Use the Settings app for a quick summary

For a simpler overview without opening multiple windows, press Windows key + I to open Settings. Go to System and click About. This page shows your device name, processor, installed RAM, system type, and Windows version in plain language.

This view is less detailed than System Information—it doesn't show processor speed or RAM type—but it's easier to read and good enough if you just need to confirm what you're working with. You can also see your Windows edition here (Home, Pro, Enterprise) and whether you're running the latest version.

Use third-party tools for detailed hardware information

If you want all your specifications in one window without switching between multiple tools, free programs like CPU-Z and GPU-Z gather everything together. read CPU-Z from cpuid.com and run it—no installation needed. It shows your processor name, speed, cores, cache, motherboard model, RAM type and speed, and Windows version on separate tabs.

GPU-Z (also from cpuid.com) shows your graphics card name, memory amount, memory type, driver version, and current temperature. These tools are read-only and safe to use; they don't change anything on your PC.

Another option is Speccy (from ccleaner.com), which displays CPU, RAM, motherboard, storage, graphics, and optical drives all on one screen. It's also free and portable. These tools are useful if you're troubleshooting, comparing your PC to another, or just want a cleaner view than Windows provides.

Understand what each specification means for performance

Your processor (CPU) speed is measured in gigahertz (GHz). A higher number means faster processing, but the architecture matters too—a newer processor at 3.5 GHz often outperforms an older one at 4.0 GHz. The number of cores tells you how many tasks it can handle at once; more cores help with multitasking and video editing.

RAM (memory) is measured in gigabytes (GB). More RAM lets you run more programs at once without slowdown. For everyday use, 8 GB is a minimum; 16 GB is standard for most people; 32 GB is useful for video editing, 3D modeling, or running many virtual machines. The RAM type (DDR4 or DDR5) affects speed, but DDR5 is only in very new PCs.

Your graphics card matters mainly for gaming and graphics work. Integrated graphics (built into your processor) handle everyday tasks fine but struggle with modern games. A dedicated card like an RTX 3060 or RX 6700 is needed for smooth gaming or professional graphics work.

Storage speed matters more than size for everyday feel. An SSD makes your PC feel fast; an HDD makes it feel slow even if the processor is powerful. Most new PCs have at least a 256 GB SSD for the operating system and programs, with additional storage for files.

Frequently Asked Questions

Where do I find my motherboard model?

Open System Information (Windows key + R, type msinfo32, press Enter) and look for "System Model" or "Base Board Product". This shows your motherboard name. You can also use CPU-Z—the motherboard tab displays the model clearly. Your motherboard manual or the manufacturer's website can tell you what features and upgrades it supports.

How do I check if my PC is 32-bit or 64-bit?

Open System Information and look for "System Type". It will say either "x64-based PC" (64-bit) or "x86-based PC" (32-bit). You can also go to Settings > System > About and look for "System type". Almost all modern PCs are 64-bit, which can use more than 4 GB of RAM and run newer software.

Can I see how hot my processor and graphics card are running?

Windows built-in tools don't show temperature. Use CPU-Z (processor temperature on the Sensors tab) or GPU-Z (graphics card temperature on the Sensors tab). You can also use free tools like HWiNFO or Open Hardware Monitor. Normal temperatures are under 80°C during use; if your PC is consistently hotter, check that fans are clean and not blocked.

What if Device Manager shows "Unknown Device"?

An unknown device usually means a driver is missing or outdated. Right-click it and select "Update driver", then choose "Search automatically for updated driver software". Windows will search online for the correct driver. If that doesn't work, visit your PC manufacturer's support website and read the latest drivers for your model.

How do I know if my RAM is running at full speed?

Open CPU-Z and click the Memory tab. Look at the "Frequency" line—this shows the actual speed your RAM is running at. Compare it to the RAM's rated speed (also listed on that tab). If the frequency is much lower, your RAM may not be fully compatible with your motherboard, or you may need to enable XMP in your BIOS settings. This is a technical adjustment; contact your PC manufacturer if you're unsure.
