Usually, the Code:43 error is not a major issue and it should not be very difficult to have it solved. Our guide will show you what you need to do in order to fix the problem so that it does not appear again.

Method 1: Update BIOS

A BIOS update is oftentimes needed for resolving certain PC issues and the Code:43 error is no exception. Here is what you need to do in order to update your BIOS.

1. First, you will have to figure out what your current version is. To do that, open the Start Menu and type system information.
2. Open the first result that gets displayed.
3. Look at the right pane – there should be an entry labeled Bios Version/Date. Your current version will be written next to it.
4. Now, go to the manufacturer site of your computer and find the downloads section.
5. Fill in the exact model of your machine. All updates available should be displayed. Download the BIOS version and install it on your PC.
6. After doing so, go back to the Device Manager and see if the yellow exclamation mark has been removed.

Method 2:Driver Re-Install

If the BIOS update did not fix your problem, then you should update your graphics card driver. However, you’d first need to ensure that Windows does not automatically install the updates for you. Therefore, you first need to stop the Windows Update service:

1. Open the Run window (Winkey+R)
2. Type services.msc and hit the Enter button.
3. When the Services window opens, take a look through the list and find the Windows Update service.
4. Double-click on it and click on Stop to stop the automatic updates.
5. Next, set the startup type to Manual. That way, WU will not start back again on its own.
6. Do not forget to start WU back on after you have fixed the NVIDIA issue.

Now, that we have that out of the way, you will need to fully uninstall your video card driver. To do that, use this program. It is advisable that you run it in Safe Mode. If you do not know how to enter Safe Mode, here is a guide that will teach you how to do it.

1. Once you have downloaded the .zip file, extract its data on your desktop.
2. Now, open the DDU.exe.
3. Another extraction is required. Once more, extract the files to your desktop. Now, double-click on the Display Driver Uninstaller.exe to open the program.
4. Follow the prompts and uninstall all graphics drivers on your PC.

After your NVIDIA drivers have been uninstalled, all that remains to be done is to download the latest updates and install them on your PC. Here is a guide for that:

1. Go to the official NVIDIA website’s driver department.
2. Fill in the model of your graphics device.
3. If you do not know your graphics card model, you can check that in the system information window that we mentioned earlier in the article. The information about your video card is in the Components>Display section, at Adapter Type.
4. Once you have searched for driver updates for your device, click on the latest one and then select Agree and Download.
5. All you have to do now is open the downloaded driver update and install it, following the prompts. After the installation is finished, go back to the Device Manager and see if the problem has been fixed.
