Just tried on freshly updated Windows 10 (with all updates from October) and same NVidia driver version (did a clean-install using installer from nvidia site) and can not reproduce the issue.

Please run blender.exe from command line (cmd.exe) with --debug-cycles command line argument. Make blender to crash and attach the full log (as a file) here. That could give some extra clues.

That's probably unrelated, this sounds more like #52064, which was a corrupted Nvidia driver installation. This can be verified by checking if another program like CUDA-Z crashes as well. In the latest builds from https:*builder.blender.org/download/ we now avoid crashing for that case (which may be the same as this report, but not sure). But GPU rendering still won't work.

I suggest a totally clean driver install:

Uninstall any NVidia, AMD and Intel graphics drivers
Download latest driver from nvidia.com
Install, with clean install option checked
Reboot computer

ok thnx. will do that tomorrow as soon as i have access to that machine.
I will also install and try with cuda-z
I use Touchdesigner heavily on that machine, and that works well. And TD make massive use of the graphics card.

What I did

Run cuda-z on unchanged pc - successful. No problem (strange)
removed all nvidia drivers
Installed all nvidia drivers as fresh installation
Run Blender, changed from blender render to cycles render. Rendered an image>sucessful

Thank you, please close this bug

The exact same problem is back again. Was a few days away from my machine. Today try to render in cycles:
Problem back exactly as described above.
Re-installed all nvidia drivers: no success, problem stays. cuda-z shows no problems, just works fine

Started blender from cmd tool and copied cmd output (see below)
Cant find the log file: Where should it be located ?

Closing as duplicate of another bug. It's still a mystery why some users are having this problem, we're trying to figure it out.
