The most common cause is a driver problem, where the driver is old, damaged, or doesn’t match the hardware. Other possible reasons include broken hardware, problems with the power supply, or wrong BIOS settings. In this article we will discuss different solutions to solve this error.
1. Run a Batch File
Running the provided batch file fixes this problem by changing system settings that affect how Windows sees the GPU. It updates certain registry entries and settings, making sure the external GPU is correctly recognized and works well.
2. Reinstall NVIDIA Drivers
When dealing with Error Code 43, reinstalling the NVIDIA drivers can restore proper communication between the operating system and your GPU. Corrupted or outdated drivers may cause the system to misinterpret the GPU’s functionality, triggering the error. Using a tool like DDU ensures that old driver remnants are removed, eliminating potential conflicts with the new installation. This step helps reset the driver environment and can resolve issues from incomplete or problematic driver updates.

3. Check Legitimacy of Nvidia Card
If the issue persists, check the legitimacy of your Nvidia card. If the card is fake, the error may continue until you replace it with a genuine one. To verify your card, install GPU-Z, an application that provides essential graphics card information. If your card is fake, GPU-Z will display a yellow warning with “[FAKE]” before the model name.
4. Disable Automatic Driver Updates from Windows
To prevent driver conflicts causing Error Code 43, manage automatic updates from Windows. Conflicts occur if Windows installs outdated drivers. You may disable updates in the Local Group Policy Editor, but proceed cautiously to avoid missing important updates. Regularly check and install the correct driver versions. If you’re using Home edition of Windows, install Group Policy Editor first.
5. Update BIOS
If your system’s firmware is outdated, it may have trouble communicating with modern hardware like your NVIDIA graphics card. Updating the BIOS helps your motherboard properly recognize and manage connected devices, including your GPU. Learn how to update the BIOS.
6. Run SFC and DISM Commands
This issue might be caused by corrupted or missing system files. An effective way to repair them is by running the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) commands. These commands scan and repair any corrupt files within the operating system. SFC focuses on fixing damaged files directly, while DISM ensures the Windows image itself is intact.
7. Perform a System Restore
If none of the solutions work, performing a System Restore is recommended. This process reverts your system to a previous state before the issue occurred, effectively undoing recent driver updates or changes without affecting your personal files.
8. Uninstall VIRTU MVP Application (if applicable)
The VIRTU MVP Application helps optimize computers for gaming by providing faster response times, better video processing, and smoother media playback. However, Nvidia does not support this application, which may lead to Error Code 43. Uninstalling the software could help resolve this issue.
