The error can affect a wide range of devices, including NVIDIA and Intel graphics cards, Bluetooth radios, USB peripherals like mice, and ethernet controllers. Because Code 43 is a general failure state, the troubleshooting steps are similar across device types, though some devices benefit from specific techniques.

What Causes Windows Error Code 43?

Code 43 appears when a device driver notifies Windows that the hardware has reported a problem. This can happen for several reasons, and understanding them helps narrow down the fix.

Key insights from the available sources help clarify what you are dealing with:

• Code 43 is frequently misinterpreted as hardware failure when it is often a driver issue.
• For graphics devices, a clean driver removal with Display Driver Uninstaller (DDU) followed by a fresh install resolves most software-related Code 43 cases.
• Bluetooth and other peripheral Code 43 errors can sometimes be fixed by disabling “Allow the computer to turn off this device to save power” in Device Manager.
• Windows 11 users may encounter Code 43 more often due to driver compatibility issues after major updates.
• If driver updates fail, the error likely indicates a genuine hardware fault, such as a failing GPU or damaged USB controller.

Update the Driver

Right-click the device in Device Manager and select “Update driver.” Choose “Search automatically for drivers.” If Windows finds a newer version, install it. If not, visit the manufacturer’s website to download the latest driver manually.

Roll Back the Driver

If the error started after a recent driver update, rolling back can help. Go to Properties > Driver tab > Roll Back Driver. This option is only available if a previous driver version is saved on your system.

Uninstall and Reinstall

Right-click the device in Device Manager and select “Uninstall device.” Check the box that says “Delete the driver software for this device” if available. Restart your computer. Windows will attempt to reinstall the driver automatically.

Disable and Re-enable

Right-click the device and select “Disable device.” Wait a few seconds, then right-click again and select “Enable device.” This forces Windows to reload the driver.

How to Fix Code 43 for NVIDIA and Graphics Cards

Graphics cards are among the most common devices to trigger Code 43. NVIDIA GPUs, in particular, are frequently affected after driver updates or Windows feature updates.

Clean Driver Installation with DDU

Standard uninstallation often leaves behind remnants that can cause conflicts. Using Display Driver Uninstaller (DDU) in Safe Mode removes all traces of the old driver. After running DDU, download the latest driver from the NVIDIA Driver Download Page and install it fresh.

Check for Windows and BIOS Updates

Microsoft’s guidance for graphics device Code 43 emphasizes keeping Windows and the system BIOS up to date. Visit your PC or motherboard manufacturer’s website for the latest BIOS version. Install all pending Windows updates before attempting driver changes.

Test on Another System

If the error persists after a clean driver install, the GPU may have a hardware defect. Testing the card in another computer can confirm whether the issue follows the card or stays with the original system.

How to Fix Code 43 on Windows 10 and Windows 11

The steps for resolving Code 43 are nearly identical on Windows 10 and Windows 11. Both versions use the same Device Manager interface and driver management tools.

Windows 11 Specific Considerations

Some users have reported Code 43 appearing after major Windows 11 updates. In these cases, rolling back the update or using System Restore can resolve the issue. Checking for driver updates from the manufacturer is especially important after a feature update.

Windows 10 Bluetooth Fixes

A Dell community thread documents Bluetooth Code 43 cases on Windows 10. Users reported success with a full power reset: shut down the laptop, disconnect the charger, and hold the power button for 10 to 12 seconds. Other fixes included driver rollback, uninstalling the Bluetooth device, and installing Dell-specific driver packages.
