Windows 10: gpu driver error 43

I accidentally deleted my gpu driver and i tried reinstalling the driver from windows update and from many different 3rd party driver apps but it always shows error 43 when updated and i have to roll back to the basic driver, i tried running ddu too then installing the update from windows update but still the same, and i wanted to try installing update from amd site but I'm not sure what my exact gpu type is and i dont even know if it will make any difference

Error 43 with my GPU

Hello carbonterry,

Thanks for using Microsoft products and posting in the community.

Error 43 with a GPU usually indicates that there is a problem with the device driver.

For this problem, Microsoft has provided a relevant solution, please refer to Fix graphics device problems with error code 43 - Microsoft Support.

From the series of information you provided, it seems that you are using both GPUs at the same time, and you can try uninstalling the old graphics card driver to see if this problem persists.

1. In the search box on the taskbar, enter device manager, then select Device Manager.
   
2. Right-click (or press and hold) the name of the device, and then select Uninstall.
   

If that still doesn't resolve the issue, go to Device Manager to disable discrete graphics or disable integrated graphics to see if the problem goes away.





You can also update your BIOS: Check if there is a BIOS update available for your computer and install it if there is. This can sometimes resolve issues with hardware components.

If these steps do not solve the problem, it is recommended that you test the hardware for problems.

Please feel free to let me know if you have any further updates, thanks.

Best Regards,

ATI hotfix drivers for crossfire setups with error 43

As part of the debugging i've been through with ati over the past 4 months the event logger being disabled does prevent the error 43 from occuring, but only because there is a problem with the driver, but without the event logger noticing the issue and flagging it to be disabled i experienced a lot of instability with the card, multi-monitor setups and moving videos from one monitor to the other were a big no-no, as were most games.

Disabling the logger only seems to prevent the gpu being disabled due to a driver error, it doesn't fix the actual problem of the error in the driver.

Your theory of something wrong with driver signature errors is interesting, sadly i'm not too familiar with driver coding and setup within windows, i'm only an app programmer and dont delve deeper than api calls.

Did the hotfix drivers still give an error for you? if so uninstall the Microsoft Visual C++ redistributable (if there are 2 versions, uninstall both, they are listed in programs and features in control panel) as that's not removed by uninstalling ati drivers but is a key part of running them and included in every driver package.
