k40 with ubuntu

I am trying to use tesla k40 on ubuntu OS. But when I turn on the PC ubuntu cannot start(I cannot access). It just stucks. But I can access windows.
If I take off gpu I can access both of the systems.
can anyone give advice what can I do.

My advice would be to look around this setup and installation forum and you will find many reports like this, some of them have instructions what to do.
