Thank, I downlaoded Cuda-Z. It crash as soon as I try to execute it. So the cuda part is definitivelly bad.
I did already try to unsintall and reinstall, even using DDU to cleanup. I did open a ticket with NVidia, I don't know if they usually respond or not to such issue.

Thanks. It does crash and generate the dump log. There is really something wrong with the cuda detection.

Might have found something. When using GPU-Z (not sure if it's info is accurate or not), it does not show that OpenCl, CUDA or PhysX are available. But they are installed and drivers when instaled clean (only graphic drivers and PhysX, no #D stuff installed)

Tested with new nVidia driver 385.28 after a clean upgrade... same result.

Additional test:
I removed my graphic card, cleaned up all drivers trace from nvidia.
rebooted
ran blender, it complained about no GPU or opengl.
Enabled the dll for software opengl and it started.
Then I installed a new GPU (1080Ti), installed the latest drivers from nvidia
Started blender and... same issue as before, it crash at the same location/thing (the cuda dll)
I can't believe I'm the only one....

I did more test on this one and ran it in the Windows debugger. Tested it with the same 3 set of drivers, including the one I know it was working before.
I'm attaching the file. Is there a command line option to disable the use of cuda ? (as a test)

On an other system with W7 it works, but not the same soft/hard of course.
If it would have been never working since the beginning under W10, I would have guessed a W10 issue, but here, I had no issues on W10 with same hardware/drivers since more than one years (even after the W10 update). And I cannot reinstall the full machine with W7 just for a test (blender is far to be the only thing installed on the main machine)

See attached file with various debug flag added:

If useful, I ran procmon on it, it seems to break when reaching the GUI/various graphical dll. I tried to uninstall, reinit and reinstall the GPU drivers, but still same result.
