How to Check Your PC Specs in Windows (and What the Numbers Actually Mean)
We are Dave's Computers, and every upgrade question, every "can my PC run this game" question, and half the calls our Somerville shop takes start the same way: what are the specs? Windows will tell you everything, once you know where to look. This guide covers every built-in tool, what each number means, and how to turn specs into a decision instead of trivia.
Four Built-In Tools, Four Levels of Detail
Windows ships with everything you need. Work through these in order of how much detail you want, on Windows 10 or 11.
The ten second check: Settings
Press Windows + I, click System, then scroll to About. Device specifications lists your processor and installed RAM, and Windows specifications shows your edition and version. Editorial guides from Tom's Guide walk this same path, and it works nearly identically on Windows 10 and 11.
The full inventory: System Information
Press Windows + R, type msinfo32, and press Enter. System Information reports the motherboard model, BIOS version, and a complete hardware rundown, the level of detail Windows Central recommends when you need everything on one screen.
The live view: Task Manager
Press Ctrl + Shift + Esc and open the Performance tab. Memory shows how much RAM you have, its speed, and critically, how many slots are in use. CPU and GPU panels show live utilization, and each drive is labeled SSD or HDD.
The graphics details: DirectX Diagnostic
Press Windows + R, type dxdiag, and press Enter. The Display tab names your exact graphics card and its video memory, the two numbers that matter most for gaming questions.
| You Want to Know | Open This | Where to Look |
|---|---|---|
| Processor and total RAM | Settings (Windows + I) | System → About → Device specifications |
| Motherboard and BIOS version | msinfo32 (Windows + R) | System Summary |
| RAM speed and slots used | Task Manager (Ctrl + Shift + Esc) | Performance → Memory |
| SSD or hard drive | Task Manager | Performance → each disk is labeled |
| Graphics card and VRAM | dxdiag (Windows + R) | Display tab |
| Windows edition and version | Settings | System → About → Windows specifications |
What the Numbers Actually Mean
Specs are only useful if they connect to what you feel at the keyboard. Here is the translation.
Cores and Clock Speed
- 1Cores carry multitasking and heavy work like exports and rendering.
- 2Clock speed carries responsiveness and most games.
- 3Neither number alone tells the story, which is why we compare against independent benchmarks, not the sticker.
Capacity and Channels
- 1Capacity: 16GB is the modern floor, 32GB is comfortable for gaming and real multitasking.
- 2Configuration: two sticks in dual channel outperform one stick of the same total size by a wide margin.
- 3Task Manager shows slots used. One stick showing means free performance is sitting on the table.
Card Model and VRAM
- 1The card model decides gaming performance more than any other line on the sheet.
- 2VRAM sets how much texture and model data the card holds at once. Modern games want more of it every year.
- 3Match the card to your monitor. 4K hardware driving a 1080p screen is the most common overspend we see.
Type Decides the Feel
- 1NVMe SSDs are dramatically faster than spinning hard drives for boot, loading, and saving.
- 2Task Manager labels every drive. HDD on the system drive explains a slow machine all by itself.
- 3Free space matters too: a nearly full system drive slows Windows down.
Can My PC Run It? Reading Game Requirements Like a Tech
Now the specs earn their keep. Every game publishes minimum and recommended requirements. Here is how to compare honestly.
Pull up the requirements for the game, then set your dxdiag and Settings numbers next to them: processor, graphics card, RAM, and storage space. Compare against the recommended list, not the minimum, because minimum usually means "technically launches." Whichever of your specs falls short of recommended is your upgrade target, no guesswork required.
When the Specs Say Upgrade
Specs turn symptoms into a shopping list. Match what you feel to what you found.
| What You Feel | What the Specs Show | The Fix |
|---|---|---|
| Everything is slow: boot, apps, saving | System drive labeled HDD, or a bargain SSD | SSD upgrade with your files migrated |
| Stutter with browser tabs and games open | 8GB RAM, or one stick in single channel | RAM upgrade to a dual-channel kit |
| Low frame rates in games | Older graphics card, low VRAM | Graphics card upgrade, power supply checked first |
| Random crashes and blue screens | Specs look fine on paper | Memory health test before any spending |
| Fast once, slow now, fans loud | Same specs as the day you bought it | Thermal service: heat, not hardware, is the thief |
⚡ Specs in hand and still not sure what they add up to? Bring the machine to the bench. Our $75 diagnostic turns the numbers into a plan, and the fee is credited toward any repair.

PC Specs FAQs for NJ Customers
The specs questions we answer most at the Somerville counter.
How do I check my PC specs on Windows 11?
Press Windows + I, choose System, then About for your processor, RAM, and Windows version. For the complete inventory, press Windows + R, type msinfo32, and press Enter.
How do I find out what graphics card I have?
Press Windows + R, type dxdiag, press Enter, and open the Display tab. Your card name and video memory are listed at the top.
How do I know if my RAM is dual channel?
Open Task Manager with Ctrl + Shift + Esc, select the Performance tab, then Memory. The slots used line tells the story: two or more sticks in matched pairs run in dual channel, one stick does not.
Can my PC run a specific game?
Compare your processor, graphics card, and RAM against the recommended requirements the game publishes. Meeting only the minimum usually delivers a rough experience, and the spec that misses recommended is your upgrade target.
What is msinfo32?
System Information, the built in Windows tool that lists your motherboard, BIOS version, processor, memory, and more on one screen. Press Windows + R, type msinfo32, and press Enter to open it.
How do I check specs on a computer that will not boot?
You cannot from inside Windows, but the hardware still tells the story. We pull drive, memory, and board details on the bench as part of the $75 diagnostic, which is credited toward any repair.
