On Boot Camp, the AMD Radeon R9 M295X is reporting "Code 43" Problems.

Question

I am on an iMac with Retina 5K display and in the latest build 9926, my graphics card is having problems. In the Device Manager the "AMD Radeon R9 M295X" is saying "Code 43: Windows has stopped this device because it has reported problems."
There has been no updates for this in Windows Updates.
I have installed the Boot Camp Support Software, but this did not fix the problem.
My graphics card worked perfectly in Build 9879.

Hi,
In my opinion, since system threw the error message: "Code 43: Windows has stopped this device because it has reported problems." There is two possible reason of this problem:
1. Driver compatibility problem, however, it's hard to make troubleshoot and fix this problem.
2. Driver installed problem, we can resolve this problem by uninstall the problematic driver and reinstall a new version. You can follow the steps of the link below to reinstall the driver:

In addition, it would be better to use driver verifier to check current graphic card driver compatibility.
