Driver/CUDA install problems on Windows 7 (8400M G)

Hi, There.

My Notebook (Fujitsu - LIFEBOOK E8410) has a graphic card (8400M G), and I successfully installed 156.16 NVIDIA DRIVER that was produced by Fujitsu. But I tried to install CUDA 2.3 for 190.38 and 2.2 for 185.85. I failed to install them. The installation said that there is not an acceptable hardware in my notebook. And, Fujitsu has no plan to update a new nvidia driver version. I cheked it via telephone.

How can I do the work? Is there a CUDA old version for 156.16? or Is there a new version driver for E8410?

Please, help me for this problem.

Thank you.
