Important: Always download drivers from the official manufacturer or your PC manufacturer’s support website. Avoid unofficial download sites, as they may provide outdated, incorrect, or modified drivers.
Fix 7: Run SFC and DISM
Corrupted Windows system files can sometimes cause driver-related problems, including devices that stop working, missing drivers, or Device Manager errors. Running the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can repair damaged system files and restore Windows components.
Step 1: Run System File Checker (SFC)
- Open Command Prompt as Administrator.
- Type the following command and press Enter:
sfc /scannow
- Wait for the scan to complete.
- Restart your computer if Windows repairs any files.
Step 2: Run DISM
If SFC reports errors that it can’t fix, run the following DISM command:
DISM /Online /Cleanup-Image /RestoreHealth
Wait for the process to finish, then restart your computer. After restarting, run sfc /scannow again to verify that all corrupted system files have been repaired.
Tip: SFC and DISM repair Windows system files, not hardware drivers. However, they can resolve driver problems caused by corrupted Windows components or failed updates.
Fix 8: Scan for Hardware Changes
If a device is missing from Device Manager or isn’t detected after updating or reinstalling its driver, force Windows to scan for hardware changes. This prompts Windows to detect connected hardware and install a compatible driver if one is available.
- Open Device Manager.
- Click Action on the menu bar.
- Select Scan for hardware changes.
- Wait while Windows scans your computer for connected devices.
If Windows detects the missing device, it will attempt to install a compatible driver automatically. If the device still doesn’t appear, restart your computer and check the physical connection if it’s an external device.
Tip: This method is especially useful after reinstalling a driver, connecting new hardware, or when a device unexpectedly disappears from Device Manager.
Fix 9: Check Device Manager Error Codes
If Device Manager displays an error code, it can help you identify the cause of the problem and choose the correct solution. To view the error code, right-click the affected device, select Properties, and check the Device status box on the General tab.
Code 28: The drivers for this device are not installed
This error usually appears when Windows can’t find a compatible driver for the device.

- Install the latest driver from the hardware manufacturer’s website.
- Run SFC and DISM to repair damaged system files.
Code 43: Windows has stopped this device because it has reported problems
Code 43 commonly affects graphics cards, USB devices, and Bluetooth adapters. It may be caused by a faulty driver, hardware problem, or firmware issue.
How to fix it:
- Restart your computer.
- Update or reinstall the driver.
- Disconnect and reconnect external devices.
- Install the latest driver from the manufacturer’s website.
- If the error persists, test the device on another computer to rule out a hardware failure.
Tip: If Device Manager displays a different error code, note the exact message shown in the Device status section before troubleshooting. The error code often provides valuable clues about the underlying problem.
Fix 10: Check Hardware Connections
If none of the software fixes resolve the problem, inspect the hardware connection. Loose cables, damaged ports, faulty adapters, or improperly seated expansion cards can prevent Windows from detecting a device or cause intermittent driver errors.
Try the following:
- Disconnect and reconnect the device securely.
- Connect the device to a different USB port or expansion slot.
- Test the device on another computer, if possible.
- Restart your computer after reconnecting the hardware.
- For internal components such as graphics cards, Wi-Fi cards, or memory modules, ensure they are properly seated (only if you’re comfortable opening your PC).
If Windows still doesn’t detect the device or Device Manager continues to display the same error after trying all the previous fixes, the hardware itself may be defective.
Tip: If the device works correctly on another computer, the problem is more likely related to your Windows installation or driver. If it fails on multiple computers, the hardware may need to be repaired or replaced.
When to Replace the Hardware
If you’ve updated, rolled back, and reinstalled the driver, installed the latest Windows updates, repaired system files, and verified the hardware connection, but the device still isn’t working, the hardware itself may be faulty.
Before replacing the device, test it on another computer if possible. If the same problem occurs on multiple systems, replacing the hardware is usually the best solution. If the device works elsewhere, the issue is more likely related to your Windows installation or system configuration.
