Why identification matters
The single most common cause of a failed driver install is downloading a package meant for a different device. Two laptops that look identical can ship with different Wi-Fi cards, and a "GTX 1660" and a "GTX 1660 Ti" use related but distinct driver branches. Before you download anything, spend a few minutes confirming exactly what is inside your computer and which build of Windows you are running.
Confirm your Windows edition and build
Press the Windows key, type "About your PC," and open the result. Look at two things:
- Edition (for example, Windows 11 Home or Windows 10 Pro).
- System type, which tells you whether you are running 64-bit Windows. Nearly all modern PCs are 64-bit, and most drivers are published only for 64-bit systems.
You can also press Windows + R, type winver, and press Enter to see the exact version and build number. Some optional drivers list a minimum Windows build, so this detail occasionally matters.
Find your PC make and model
If you bought a prebuilt desktop or a laptop, the manufacturer (Dell, HP, Lenovo, ASUS, Acer, and others) publishes drivers keyed to a specific model or service tag. To find yours:
- Press Windows + R, type msinfo32, and press Enter. The System Manufacturer and System Model fields identify the machine.
- Laptops usually print a model or serial number on a sticker on the underside.
- Many vendors also let you look up the exact configuration from a service tag or serial number on their support site.
Write these values down. When you visit an OEM support page, entering the model or serial is the most dependable way to get the drivers matched to your exact configuration.
Identify individual components
For internal parts such as the graphics card, network adapter, or storage controller, Device Manager and its Hardware IDs are the ground truth.
- Press Windows + X and choose Device Manager.
- Expand a category, right-click a device, and choose Properties.
- On the Details tab, change the property drop-down to Hardware Ids.
The Hardware ID contains a vendor ID (VEN_) and device ID (DEV_) that uniquely describe the chip. If a device shows up as "Unknown device," the Hardware ID is often the only clue you have, and searching the VEN/DEV values on a reputable hardware database can reveal the manufacturer.
Build a custom PC? Check the board and GPU separately
On a self-built desktop, there is no single "PC manufacturer." Instead, gather drivers from the makers of each part:
- Motherboard vendor (ASUS, Gigabyte, MSI, ASRock) for chipset, audio, and LAN.
- Graphics card chip vendor (NVIDIA, AMD, or Intel) for the GPU.
- Peripheral vendors for keyboards, mice, headsets, and capture devices.
You can read the motherboard model from msinfo32 under BaseBoard Product, or from the printed silkscreen on the board itself.
A quick checklist before you download
- Windows edition and 64-bit confirmed.
- PC make and model, or motherboard model, recorded.
- Component Hardware IDs noted for any device you are unsure about.
- Service tag or serial number ready for OEM lookups.
When you do not need to identify anything
If a device already works and you have no specific problem to solve, you may not need a new driver at all. Windows Update handles most routine cases automatically. Identification becomes important when you are troubleshooting a fault, enabling a feature, or setting up a fresh Windows installation where a device is missing.
