Since the Win 10 update I get a white box message mid screen on booting up.

It says Run DLL

Then "there was a problem starting NVCPL.DLL.  App failed to start because a side by side configuration is incorrect.

Please see the app event log or use the command line sxstrace.exe tool for more detail."

If I just use the computer normally, there does not seem to be any irregularity, or any problems.

I know little about tracking down what needs to be done, and then doing it.

Any help would be appreciated!  Thanks.
