We had research on this and discovered the error could be caused due to several reasons, including those mentioned below:-
Lucid VIRTU MVP Software- Lucid VIRTU MVP is software that offers computer visuals with a faster response time but as per the Nvidia reports, using Lucid VIRTU MVP can bring many errors, including this one.Hardware Issue– The error could appear due to the hardware issues such as a wrong inserted graphics card and its cables. So before moving out, make sure to check that the graphics card and cables are correctly connected. You can also check the minimum watt of your power supply and how much your graphics card takes from it.Outdated Motherboard Bios- Having outdated bios can be one of the main reasons as it can cause errors.Outdated and Wrong Installed Drivers- If you have installed your graphics driver incorrectly, you may encounter this error. Please ensure the drivers you have are not obsolete or missing, as it can trigger error code 43.Defective System Files- If your Windows has corrupted files that cause error code 43, you must run some system commands to repair them.
1. Run a Batch File To Resolve Error Code 43
We have found an effective method that worked for almost every user encountering Error Code 43. Below we attached a batch file created explicitly for fixing error code 43 against Nvidia eGPU running on a mPCIe, EC, M.2, LUA interface, or desktop PCIe slot. Below are the steps to run a batch file.
2. Uninstall VIRTU MVP Application
VIRTU MVP Application allows users to optimize their computers for the best gaming experience. The application offers faster response time, video processing, and smoother media playback. However, Nvidia does not support the VIRTU MVP Application, which can be why you are getting Error Code 43. To uninstall the VIRTUP MVP application, press the Windows + R keys at the same time
3. Reinstall NVIDIA Drivers
As it turns out, a corrupted graphics driver can be the sole reason for this issue. Having corrupted drivers decreases GPU performance and brings many errors such as this one. So first, we need to remove the graphics driver properly. Many users use the device manager to remove their drivers. Still, some files cannot be removed properly and are being left behind, which can cause errors because when we remove drivers, we want to delete them permanently. Apparently, From the device manager, it does not happen, and when we install new drivers, they conflict with each other, which is terrible and can cause problems. To remove drivers properly, we use DDU (Display Driver Uninstaller), allowing us to remove drivers without any files left behind.
3.1 Uninstall Graphics Driver
3.2 Install Graphics Driver
We have mentioned the almost similar steps for installing the graphics driver, if you have AMD or INTEL graphics card, you either follow the below steps:-
4. Check legitimateness Of Nvidia Card
If the issue is still there, you may need to check the legitimacy of your Nvidia Card, if your card is fake, this error could arise until you change the graphics card. In this case, you need to ensure that your card is legit. For that, you have to install GPU-Z, an application that provides vital graphics card information. If your graphics card is fake, you will get a yellow warning with the [FAKE] before the model name of your graphics card.
5. Disable Automatically Updating Drivers From Windows
Another solution for this error is to disable automatic updates from windows as it can cause a conflict of drivers, which occurs when windows think it is the latest driver and install the outdated one. The driver you have already installed can conflict with a driver that windows installed. It is called driver conflict that can cause Error Code 43. To avoid this, you have to disable automatic driver updates from the Local Group Policy Editor. Below are the steps that will help you to disable automatic updates:-
6. Update BIOS
If the issue is still there, try updating bios as it can aid in fixing the problem. If your bios is outdated, try to update it from the manufacturer’s website and follow all the instructions they mentioned.
7. Run SFC and DISM Commands
Corrupted or missing system files are also included in causing Error Code 43. The easy way to repair corrupted files is by running commands to restore Windows images and files. These commands contain the DLL package and the files that will replace with the corrupted or missing ones.
8. Revert System to Previous Restore Point
If none of the methods has worked, we recommend you restore Windows to a working condition. It requires a restore point created before you encounter the error message. Above, we have compiled all the solutions that have the potential to fix Error Code 43. If none of the methods worked, we recommend you take your laptop or computer to a repair shop as the problem might come from the hardware.
