Solution:

- Check your GPU:

- Check Nvidia’s table of CPU – CUDA (Code Generation) Version

https://developer.nvidia.com/cuda-gpus

- In MSVS 2010, go to Project Properties –> CUDA C/C++ –> Device –> Code Generation

change Compute_xx and SM_xx to the number in that table without the decimal point

NOTE: it is possible that the exact version is not supported by your version of NSight/CUDA toolkit, in which case, go back one on the version number and try again.
