How to troubleshoot Error Code 43 for Nvidia Graphics Card on Windows 10
To troubleshoot Error Code 43 for your Nvidia graphics card on Windows 10, you can try the following two methods:
Method 1: Update or reinstall Nvidia drivers
One of the most common causes of Error Code 43 is a problem with your Nvidia drivers. To fix this, you can update or reinstall your Nvidia drivers using the following steps:
Step 1: Download Display Driver Uninstaller and the latest Nvidia drivers
Display Driver Uninstaller (DDU) is a tool that can help you completely remove your Nvidia drivers and software from your system. You can download it from here. You also need to download the latest Nvidia drivers for your graphics card from here. Make sure you choose the correct model and operating system.
Step 2: Boot into Safe Mode and uninstall Nvidia drivers and software
Safe Mode is a diagnostic mode that allows you to troubleshoot Windows problems without loading unnecessary drivers or programs. To boot into Safe Mode, follow these steps:
Click on the Start menu and select Settings.
Click on Update & Security and then Recovery.
Under Advanced startup, click on Restart now.
After your computer restarts, choose Troubleshoot > Advanced options > Startup Settings > Restart.
Press F4 to enter Safe Mode.
Once you are in Safe Mode, run DDU and select Nvidia as the device type. Then click on Clean and restart. This will remove all traces of Nvidia drivers and software from your system.
Step 3: Boot into normal mode and install Nvidia drivers and software
After your computer restarts in normal mode, run the Nvidia driver installer that you downloaded in Step 1. Follow the instructions on the screen and choose Custom installation. Check the box that says Perform a clean installation. This will install the latest Nvidia drivers and software on your system.
After the installation is complete, restart your computer and check if Error Code 43 is resolved.
Method 2: Reflash BIOS to a known working version
Another possible cause of Error Code 43 is a problem with your BIOS. BIOS stands for Basic Input/Output System and it is a firmware that controls how your motherboard communicates with your hardware devices. Sometimes, updating or changing your BIOS can cause compatibility issues with your graphics card. To fix this, you can reflash your BIOS to a known working version using the following steps:
Step 1: Download the BIOS file from your motherboard manufacturer's website
You need to download the BIOS file that matches your motherboard model and version from your motherboard manufacturer's website. For example, if you have an ASRock Z170 Pro4 motherboard, you can download the BIOS file from here.
Step 2: Run the BIOS flash utility with the /nodate option
The BIOS flash utility is a program that can help you update or restore your BIOS. You can find it in the same folder as the BIOS file that you downloaded in Step 1. To run the BIOS flash utility with the /nodate option, follow these steps:
Open a command prompt as administrator.
Navigate to the folder where the BIOS file and the flash utility are located.
Type winflash /nodate bios.xxx (replace xxx with the BIOS file name) and press Enter.
Follow the instructions on the screen and wait for the process to complete.
The /nodate option allows you to flash an older BIOS version without checking the date. This can help you fix compatibility issues with your graphics card.
Step 3: Restart your computer and check if Error Code 43 is resolved
After the BIOS flash is done, restart your computer and check if Error Code 43 is resolved. If not, you may need to try another BIOS version or contact your motherboard manufacturer for support.
