How To Fix Code 43 Error – Easy Step-By-Step Guide

RAM speeds

The great thing about a computer is that eventually, unless you're really lucky or purchase a new build every year, something is going to go majorly wrong and it's going to affect how you use your device. I particularly like it when you're in the middle of a game of PUB:G, in the final 4, and your graphics card decides to stop working just as you're about to snipe one of the remaining players. That's the best! But anyway....

The point I'm trying to make is that once in a while, something goes wrong and you simply can't get it working again. Well, that's where WEPC likes to extend a helping hand in your direction. Unfortunately for some, this article is going to cover the Code 43 error, usually relating to a graphics card device.

In the following article, we'll walk you through a couple of different methods of how to fix the code 43 error in case one doesn't work. So, without any further ado, let's get into the first method.

Do I Have A Code 43?

Before we discuss how to fix a Code 43, firstly, it's worth explaining how to find out whether or not your device even has a code 43. This is the easiest method of finding out whether your device has been stopped and takes just a few simple steps.

Firstly, go to the Windows Search bar and type 'Device Manager'.

Find your device

Once in Device Manager, simply find the 'Display Adapters' drop down and you will see your graphics card.

Check Your GPU Device

(A quick note - If your card does have a code 43, you will see an amber triangle over your device with an exclamation mark.)

Finally, right click on your graphics card and select 'Properties'.

Once inside properties you will see the 'Device Status' tab where it will say whether or not you have a code 43. See image.

Fixing A Code 43 Error - Method 1

The first step we're going to take in this fixing process is to completely reinstall the device itself. Any error made by Windows will be resolved by doing this. So let's get started.

Follow the steps above to find your graphics card in Device Manager. (this also works without any other device which has a code 43)

Right-click the device and select 'Uninstall Device'.

Code 43 Uninstall device

Once you've selected 'uninstall device' you will be asked to confirm the uninstallation of the device. Click OK.

Code 43 confirm uninstall

Allow Windows to fully uninstall the selected device. Once Windows has completed this task it may ask you to restart. If so, restart the PC and reopen the Device Manager tab.

If not, go to the 'Action tab' and select 'Scan for hardware changes'.

Code 43 scan for hardware changes

Windows will then scan for any unused, or new, hardware and reinstall the device. Most of the time this will resolve your issue. To check whether or not these steps have been successful, simply look at the graphics card in the device manager window. If it doesn't have the amber triangle over the tab, you're all fixed!

Fixing A Code 43 Error - Method 2

Most of the time, a Code 43 error is driver related, so, if the above steps didn't fix your problem, an entire reinstall of the drivers should do the trick.

We will be using the device manager again for the start of this process.

When in the device manager, right click the broken device and click properties.

Code 43 device properties

Once inside the device's properties tab. Select the 'Driver' tab. Found next to the general tab. Once inside Driver, click the 'Update Driver' button. See image.

code 43 update driver

A update driver window will pop up asking you how you would like to search for the latest drivers. Click the 'Search automatically for updated driver software' tab.

Code 43 Confirm driver update

Windows will then do 1 of 2 things. Firstly it will search for the latest drivers. If you don't have the latest drivers then follow the steps provided and install them. Restart your PC and this should fix any Code 43 issues you are having.

However, sometimes Windows will come back and say that you have the latest version of the device drivers already installed. In this case. Follow the steps below to do a manual uninstall and reinstall of the drivers.

Using A DDU

In some cases, Windows won't be able to perform a sufficient enough driver reinstall. This might affect the device and not remove the code 43 error. In this case, we recommend using a DDU to fully cleanse your PC of any old drivers.

So, what is a DDU you ask? Good question.

It's basically a display driver uninstaller and is a unique piece of software which you download, for free, and use to fully clean your computer of any and all old drivers which might be causing you a problem.

Using this will remove the old drivers fully, after which you can go back into device manager and reinstall the drivers again. Just follow method 2 after the uninstall section.

Furthermore, we would recommend getting Nvidia experience to install the latest drivers over windows for Nvidia users. It has a bunch of tools within its software and makes life much easier than messing around in device manager.

Is It Worth Reformatting?

I wouldn't usually recommend doing a full reformat to try and fix a code 43 error. However, sometimes it can be worth doing, especially if you're thinking about returning a product and want to exhaust every possible problem.

Doing a reformat though is probably not going to fix the issue, unfortunately. If you have followed all the above steps, and your PC is still having issues, you may be one of the unlucky few who have purchased a faulty hardware device.

Most of the time you can speak to the manufacturer and they will issue you a refund or new device though, so not all bad news!

Anyway, I hope this helped, if you have any questions about the guide then feel free to leave a comment below and one of the team will get back to you as quickly as possible!
