Windows 10: Code 43 Error Won't Go Away

AndersonStark · Mar 17, 2024

Hello! My desktop PC suddenly started having low resolution and flickering green lights across it. In device manager, my geoforce RTX 3060 has a code 43 error and I cannot fix it. I've uninstalled the drivers with ddu, reinstalled from NVidia, switched cables but nothing works. Can someone please help me?

:)

Advice from Microsoft: Graphics device driver error code 43

Windows stopped your device because it reported problems. To fix it, try the following:

Select the Start button, then in the search box next to Start, type device manager and select Device Manager from the list of results.

Find the problematic device in the list (it will often have a yellow exclamation point icon next to it).

Press and hold (or right-click) the name of the device, and select Properties. In Properties, select the Driver tab, select Roll Back Driver, then follow the steps. If the button is unavailable, that means there's no driver to roll back to.

Select Uninstall device and then select Uninstall.

At the top of the list of devices in Device Manager, press and hold (or right-click) the name of your PC, then select Scan for hardware changes. This reinstalls the device driver.

To see if this fixed the problem, press and hold (or right-click) the name of the device again and select Properties. On the General tab, under Device status, you should see This device is working properly. If you don’t see this message, refer to the documentation that came with the device or contact the manufacturer.
