Understanding Error Code 43

Error code 43 is displayed in Device Manager when Windows detects that a device is not functioning correctly or has encountered significant hardware issues. Typically, this error points to a problem with the graphics card, prompting Windows to disable the device to prevent further issues. You will see the message "Windows has stopped this device because it has reported problems. (Code 43)" in the device's properties.

The primary reasons for this error are often faulty drivers or damaged hardware. If the error is due to corrupted or missing drivers, there's a good chance it can be resolved. However, if the hardware is physically damaged, you may need to consider repair or replacement. Let's start with some software-based solutions to tackle error code 43.

1. Reset the Power Supply

A basic restart won't likely resolve error code 43. You should fully discharge your PC or laptop's power and then check if the problem persists.

• For a PC: power it down, disconnect all cables, and press the power button for at least 30 seconds. Power it back on and check if the issue has been resolved.
• For a Laptop: turn it off, disconnect all cables, remove the battery, and reinsert it after a few minutes. If the battery is not removable, hold the power button for about 30 seconds to reset the power.

Restart your system and verify if the error still appears in Device Manager.

Interesting Fact: Graphics cards aren't just for internal use anymore! Explore external graphics cards and decide if they're worth the investment.

2. Deactivate and Reactivate the GPU

Sometimes, simply deactivating and reactivating your graphics card can solve the problem, as it prompts Windows to reconfigure the device.

1. Hit Win X and choose Device Manager.
2. Right-click your graphics card under "Display adapters" and select "Disable device."

3. Confirm by selecting "Yes" when prompted with the message: "Disabling this device will cause it to stop functioning. Do you really want to disable it?"

4. The graphics card icon will show a black arrow or red "X" indicating it's disabled. Right-click it again and select "Enable device."

5. This action reactivates your graphics card. Right-click it and choose "Properties" to check if error code 43 has vanished.

6. Revert to a Prior System Restore Point

If you've recently installed new software, updated device drivers, or altered system settings, these changes might be the cause of error code 43.

In this scenario, reverting your system to a previous state before these changes might help. Use System Restore, provided you have available restore points.

1. Click the search icon on your taskbar and type "Create a restore point." Select the top result to access the "System Properties" page.

2. Click the "System Restore" button to revert your system to either the recommended restore point or another of your choice.

3. Note that "System Restore" isn't enabled by default for non-system partitions. To enable it, open System Properties, choose the drive you wish to create a restore point for, and click "Configure." Select "Turn on system protection" at the top.

4. After restoring the system, the error should no longer be present.

Tip: Ensure your Windows hardware functions smoothly by installing unassigned drivers when necessary.

4. Revert Device Drivers

If reverting to a previous system state doesn't fix the error, follow these steps to manually revert the GPU driver:

1. Open Device Manager as previously described.
2. Double-click the problematic device, which in this case is the graphics card.

3. Navigate to the "Driver" tab and click "Roll Back Driver."

4. Choose your reason for rolling back and click "Yes" to revert to the last driver Windows has for the device.

5. If prompted, restart your computer by selecting "Yes." Your system will reboot with the previous driver version.

6. Check Device Manager to see if error code 43 is resolved. If not, proceed to the next solution.

7. Update Your Windows

Updating Windows can sometimes resolve issues that arise from underlying problems in your system. If you're not on the latest Windows version, follow these steps to update:

1. Press Win I to open Settings.

2. Select "Windows Update" from the left side. If updates are available, they'll appear on the right. If not, click "Check for Updates." On Windows 10, navigate to "Settings -> Update & security" to check for updates.

6. Reinstall GPU Drivers

If your GPU still has issues, you'll need to reinstall its drivers.

First, uninstall the current drivers using specialized software like Display Driver Uninstaller (DDU). You might find our guide on removing old Windows drivers helpful.

Afterward, visit your GPU manufacturer's website to download the latest drivers.

If the error persists in Device Manager, consider more advanced solutions.

7. Update Your BIOS

Updating the BIOS should be one of your final attempts to resolve error code 43, as it can introduce new issues.

While it might seem complex, you can follow our detailed BIOS upgrade guide to safely update your BIOS.

8. Inspect Your GPU Connection

Sometimes, simply reconnecting your GPU cables can fix the error. Another option is to remove the graphics card and reinstall it.

Caution: Only attempt this if you're familiar with the process. Otherwise, seek help from a professional.

1. Turn off your PC and open the case to access the card.
2. Carefully remove the graphics card by unscrewing it from the case and releasing the PCI-e slot's tab.

3. Reinsert the GPU into the PCI-e slot.

4. Restart your system and check Device Manager to see if the error is resolved.

5. Reinstall Windows

As a last resort, installing a fresh copy of Windows can eliminate any drivers, system settings, or conflicting programs causing the error. If nothing else works, refer to our guide on reinstalling Windows without losing data.

If error code 43 persists after reinstalling Windows, it's likely your graphics card is damaged or dead. In this case, you may need to RMA it if it's under warranty, or consult a repair professional. If repair isn't viable, you might need to replace the graphics card.

Frequently Asked Questions

What can cause physical damage to a GPU?

Physical damage to a graphics card is often due to overheating, which can result from inadequate cooling, dust buildup, or running games beyond the card's capabilities.

How do I know if my GPU is physically damaged?

Signs of a failing GPU include frequent crashes, visual artifacts like colored lines, and unusual noises.

Can a GPU be repaired?

If the core or memory of a GPU is damaged, repair is typically not possible. However, components like capacitors or power controllers might be fixable by a skilled technician, though the card's lifespan may be limited afterward. Often, it's more cost-effective to replace the GPU.

Should I clean my GPU?

Regularly deep-cleaning your GPU can prevent dust accumulation, reduce overheating risks, and extend its lifespan. This involves disassembling the heatsink and fans, using compressed air to clear dust, cleaning stubborn stains with isopropyl alcohol and Q-tips, and reapplying thermal paste.
