How to Fix a Device Not Working in Windows (Driver Updates & Troubleshooting)

Introduction

Few things are more frustrating than plugging in a device—like a printer, USB drive, webcam, or keyboard—only to find it doesn’t work. Most Windows device issues are caused by outdated drivers, power settings, or hardware conflicts.

In this guide, we’ll go step by step to fix device problems in Windows, whether your device isn’t recognized, is malfunctioning, or is completely unresponsive.

Step 1: Check Basic Connections & Restart Your PC

Before troubleshooting drivers, rule out simple fixes:
✅ Unplug and replug the device into another USB port.
✅ Try a different cable (if applicable).
✅ Restart your PC (this fixes many issues!).
✅ Test the device on another PC to rule out hardware failure.

🚀 Pro Tip: If your device is USB-powered:

Step 2: Check Device Manager for Errors

Device Manager lets you see if Windows detects the device and whether drivers are missing or corrupted.

How to Open Device Manager

1️⃣ Press Windows + X, then select Device Manager.
2️⃣ Look for your device under categories like:

• Universal Serial Bus controllers (USB devices)
• Imaging devices (Cameras, scanners, etc.)
• Network adapters (Wi-Fi, Bluetooth, Ethernet, etc.)
• Other devices (Unknown or unrecognized devices)

Check for Warning Symbols

⚠️ Yellow Exclamation Mark (!) → Driver issue or conflict
❓ Unknown Device → Windows doesn’t recognize it
🚫 Gray/Disabled Device → Device is turned off

💡 If you see an error, continue to Step 3.

Step 3: Update or Reinstall the Device Driver

Drivers allow Windows to communicate with hardware. If outdated or corrupted, they can prevent devices from working.

How to Update a Driver in Windows

1️⃣ Open Device Manager, right-click the device.
2️⃣ Click Update driver → Search automatically for drivers.
3️⃣ If an update is available, install it and restart your PC.

How to Manually Reinstall a Driver

1️⃣ In Device Manager, right-click the device → Select Uninstall device.
2️⃣ Restart your PC → Windows will attempt to reinstall the driver automatically.

If Windows says your driver is up to date but the device still isn’t working, move to Step 4.

Step 4: Download the Latest Driver from the Manufacturer

Some devices require manufacturer drivers instead of Windows updates.

How to Find the Right Driver

1️⃣ Go to the manufacturer’s website (NVIDIA, Intel, Logitech, Realtek, etc.).
2️⃣ Search for your device model.
3️⃣ Download and install the latest Windows-compatible driver.
4️⃣ Restart your PC.

❌ Avoid downloading drivers from third-party sites—they may contain malware!

Step 5: Check Windows Updates

Sometimes, Microsoft releases driver updates through Windows Update.

How to Check for Updates

1️⃣ Open Settings → Update & Security → Windows Update.
2️⃣ Click Check for updates and install any pending updates.

---

Step 6: Run the Windows Troubleshooter

Windows has built-in troubleshooters that can detect and fix some hardware issues.

How to Run a Troubleshooter

1️⃣ Open Settings → Update & Security → Troubleshoot.
2️⃣ Select Additional troubleshooters.
3️⃣ Choose the relevant category (Hardware, USB, Bluetooth, etc.) and run the troubleshooter.

Step 7: Adjust USB Power Settings (For USB Devices)

If a USB device (mouse, keyboard, external hard drive) randomly disconnects, Windows Power Management might be turning off the USB port.

How to Disable Power Saving for USB Devices

1️⃣ Open Device Manager → Expand Universal Serial Bus controllers.
2️⃣ Double-click each USB Root Hub → Go to the Power Management tab.
3️⃣ Uncheck “Allow the computer to turn off this device to save power.”
4️⃣ Click OK and restart your PC.

---

Step 8: Try a System Restore (If the Device Recently Stopped Working)

If your device was working fine but stopped after a Windows update, a System Restore can revert changes.

How to Restore Windows to an Earlier Date

1️⃣ Open Control Panel → Recovery → Open System Restore.
2️⃣ Select a restore point from before the issue started.
3️⃣ Click Next → Finish and let Windows restore your system.

⚠️ Note: This will undo recent system changes but won’t delete personal files.
