Where to find your PC specs on Windows
The fastest way to see your PC's specifications is through the System Information window. Press Windows key + Pause/Break on your keyboard, or right-click "This PC" on your desktop, select Properties, and look at the window that opens. You will see your processor name, installed RAM, and system type (32-bit or 64-bit) right there.
For more detailed information, open the Run dialog by pressing Windows key + R, type msinfo32, and press Enter. This opens System Information, which lists your processor, RAM, BIOS version, and installed devices. You can also search "System Information" directly in the Windows search bar.
If you need to know what graphics card you have, right-click your desktop and look for an option like "NVIDIA Control Panel" or "AMD Radeon Settings." If neither appears, open Device Manager by pressing Windows key + X and selecting it from the menu, then expand "Display adapters" to see your GPU.
Key Takeaways
- Windows System Information (accessible via Windows key + Pause/Break or msinfo32) shows your processor, RAM, and system type in seconds.
- Device Manager reveals your graphics card, storage drives, and other hardware by expanding each category.
- For storage space used and available, right-click your C: drive in File Explorer and select Properties.
- Third-party tools like CPU-Z and GPU-Z provide detailed specifications if you need technical details beyond what Windows shows.
Checking storage and drive information
To see how much storage space you have and how much is in use, open File Explorer, right-click your C: drive (or whichever drive you want to check), and select Properties. A window will show total capacity, used space, and free space in both gigabytes and a visual bar.
If you want to know what type of storage you have—whether it is a traditional hard drive (HDD) or a solid-state drive (SSD)—open Device Manager, expand "Disk drives," and look at the name. SSDs usually say "SSD" in the name; hard drives often say "SATA" or just list a brand name. You can also right-click the drive and select Properties to see additional details.
Using Device Manager for a complete hardware list
Device Manager is built into Windows and shows every piece of hardware your PC recognizes. Press Windows key + X and select Device Manager, or search for it directly in the Windows search bar. Each category can be expanded by clicking the arrow next to it.
Look here for your graphics card (under "Display adapters"), sound card (under "Sound, video and game controllers"), network adapter (under "Network adapters"), and any USB devices you have connected. If a device has a yellow warning triangle, it means Windows does not have the correct driver installed for it.
Third-party tools for detailed specifications
CPU-Z is a free tool that shows detailed information about your processor, including its speed, cores, cache, and voltage. read it from cpuid.com, run the installer, and open the program—no additional setup is needed. The Processor tab shows everything about your CPU; the Memory tab shows your RAM type and speed.
GPU-Z, also free from techpowerup.com, displays detailed graphics card information including memory amount, memory type (GDDR6, GDDR5X, etc.), and clock speeds. These tools are useful if you are troubleshooting performance issues or checking whether your hardware matches what you paid for.
Both tools are portable, meaning you can run them without installing anything. They are safe to read from their official websites and do not require registration or payment.
Finding your motherboard and BIOS version
Your motherboard model and BIOS version appear in System Information. Open msinfo32 (press Windows key + R, type msinfo32, press Enter), and look for "System Model" and "BIOS Version/Date" in the list. The system model tells you the exact motherboard your PC has.
This information matters if you need to update your BIOS, install a specific driver, or check whether your motherboard supports a hardware upgrade. You can search your motherboard model online to find its manual and specifications.
Checking RAM type and speed
Windows System Information shows how much RAM you have installed, but not the speed or type. To see those details, use CPU-Z: read it, open it, and click the Memory tab. You will see the amount of RAM, its type (DDR4, DDR5, etc.), and its speed in MHz.
You can also open Device Manager, expand "Memory technology devices," and look for your RAM modules listed there, though this usually only shows the amount, not the speed. If you need to add more RAM or replace a module, knowing the type and speed helps you buy compatible memory.
What to do if you cannot find a specification
If a piece of hardware does not appear in Device Manager or System Information, Windows may not have the correct driver installed. Check the manufacturer's website for your PC model (if it is a laptop or prebuilt desktop) or your motherboard manufacturer's website, and read the latest drivers.
If you built your PC yourself and do not remember what you installed, look inside the case—most components have their model number printed on them. Take a photo of the motherboard, graphics card, and RAM sticks, and you can search those model numbers online to find their specifications.
Frequently Asked Questions
How do I know if my PC is 32-bit or 64-bit?
Open System Information (Windows key + Pause/Break) and look for "System Type." It will say either "x86-based PC" (32-bit) or "x64-based PC" (64-bit). Most modern PCs are 64-bit, which allows them to use more than 4 GB of RAM.
What is the difference between CPU and processor?
They are the same thing. CPU stands for Central Processing Unit. When you see "processor" in System Information, it is referring to your CPU—the chip that does the main calculations for your computer.
Why does my PC show less RAM than I installed?
If you installed 16 GB but Windows shows less, one stick may not be fully seated in its slot. Power off your PC, open the case, and press down firmly on each RAM stick until the clips on both ends click into place. Restart and check System Information again.
Can I check my specs without opening my PC?
Yes. System Information, Device Manager, and CPU-Z all show your specs without opening the case. You only need to open the case if you want to physically inspect components or reseat RAM or cables.
What does "driver" mean when I see it in Device Manager?
A driver is software that tells Windows how to communicate with a piece of hardware. If a device has a yellow warning triangle, it means Windows does not have the right driver, and the hardware may not work properly until you install one from the manufacturer's website.
