How to Check Drivers on a PC: A Complete Guide

Drivers are the invisible glue between your hardware and your operating system. When they work, you never think about them. When they don't, things get frustrating fast — crashes, missing devices, poor performance, or hardware that simply won't respond. Knowing how to check your drivers is one of the most practical PC maintenance skills you can have.

What Exactly Is a Driver?

A device driver is a small software program that tells your operating system how to communicate with a specific piece of hardware. Your GPU, network adapter, audio card, USB controllers, printer — each one depends on a driver to function correctly.

Drivers sit between the hardware layer and the OS layer. Without the right driver, Windows (or Linux) has no reliable way to send instructions to that device. Some drivers are generic and built into Windows itself. Others are manufacturer-specific and need to be installed separately for full functionality.

Method 1: Check Drivers Using Device Manager 🖥️

Device Manager is the most direct built-in tool for viewing and managing drivers on Windows.

How to open it:

• Press Windows + X and select Device Manager
• Or press Windows + R, type devmgmt.msc, and hit Enter

Once open, you'll see a full list of hardware categories. Expand any category — say, Display Adapters or Network Adapters — to see the specific devices installed.

To check a driver's details:

1. Right-click the device
2. Select Properties
3. Click the Driver tab

You'll see:

• Driver Provider — who made the driver (Microsoft, NVIDIA, Intel, etc.)
• Driver Date — when it was published
• Driver Version — the specific version number installed
• Digital Signer — confirms the driver has been verified

What Warning Signs Look Like

In Device Manager, a yellow triangle with an exclamation mark next to a device means there's a problem — often a missing, corrupted, or incompatible driver. A red X means the device is disabled. No icon at all generally means the driver is loaded and functioning normally.

Method 2: Use the System Information Tool

For a broader overview without diving into individual devices, System Information gives you a high-level snapshot.

• Press Windows + R, type msinfo32, and press Enter

Navigate to Components in the left panel to explore hardware categories. This tool is more useful for logging what's installed rather than actively managing drivers.

Method 3: Check Drivers via PowerShell or Command Prompt

For users comfortable with the command line, PowerShell offers a powerful way to list all installed drivers at once.

Run this command in PowerShell (as Administrator):

Get-WmiObject Win32_PnPSignedDriver | Select-Object DeviceName, DriverVersion, Manufacturer | Format-Table 

This outputs a table of every signed driver — including device name, version, and manufacturer — all at once. It's especially useful if you want to audit a machine quickly or export the data for review.

A similar command in Command Prompt:

driverquery 

This lists all installed drivers with their module name, display name, driver type, and link date. Add /v for verbose output or /fo csv to export as a CSV file.

Method 4: Check for Outdated or Problem Drivers Through Windows Update

Windows Update sometimes includes driver updates alongside OS patches, though not always the most current manufacturer versions.

To check:

1. Go to Settings > Windows Update
2. Click Advanced Options
3. Select Optional Updates
4. Look for a Driver Updates section

If driver updates appear here, they've been tested for general compatibility with Windows — though they may lag behind what the manufacturer directly offers.

Key Variables That Affect Which Drivers You Need

Not every PC has the same driver requirements. Several factors determine what's relevant for your machine:

Generic vs. Manufacturer Drivers: The Practical Difference

Windows will often install a generic driver automatically when it detects new hardware. These drivers provide basic functionality — your GPU will display an image, your network card will connect — but they typically lack advanced features.

A manufacturer-specific driver (downloaded from NVIDIA, AMD, Intel, Realtek, etc.) usually unlocks:

• Full performance capabilities
• Control panel software and tuning options
• Better stability under demanding workloads
• Support for device-specific features

For common hardware like a webcam or basic USB peripheral, a generic driver may be entirely sufficient. For a discrete GPU or a high-end audio interface, the difference between generic and manufacturer drivers can be significant.

What Outdated Drivers Can Actually Cause

It's worth being specific here. An outdated or incompatible driver isn't just a theoretical risk. It can cause:

• Blue Screen of Death (BSOD) — often tied to GPU or chipset driver issues
• Device not recognized — especially after Windows updates
• Audio or display problems — stuttering, no sound, wrong resolution
• Network instability — drops or reduced speeds on Wi-Fi adapters
• Performance degradation — particularly with graphics drivers on gaming PCs 🎮

The Spectrum of Situations You Might Be In

The right approach to driver management varies depending on your setup:

A casual home user on a manufacturer-built laptop (Dell, HP, Lenovo) may find that Windows Update and the manufacturer's support tool handle everything adequately.

A gamer or creative professional on a custom-built desktop likely needs to actively monitor GPU driver updates from AMD or NVIDIA, where each release can meaningfully affect performance or fix known bugs.

An IT administrator managing multiple machines may lean on PowerShell auditing, group policy, or third-party management tools to track driver states across a fleet.

A user after a fresh Windows install often finds that several devices are running on generic drivers until manufacturer packages are installed manually.

The tools to check your drivers are the same across all these scenarios. What you do with that information — and how urgently — depends entirely on what hardware you're running, how you use it, and what problems, if any, you're already experiencing.
