What crashes? Maya, or the render?
If it is the render that crashes, can you get an Arnold log? Set the verbosity level to Info
See Help | Diagnostics | Autodesk
Assuming you are on Windows, then when you start Maya, open Windows > Output Window.
You should an Arnold log, which looks something like this:

Please post the log header for your machine, so we know some of the details about your system.
Also, does this happen with any scene, even an empty scene?
