Why the output is "! kernel execution error." when I run the SDK example simpleCUBLAS

The output is “!!! kernel execution error.” when I run the SDK example simpleCUBLAS using VS2005 under windows. Why?? What do I need to do to get the right answer for simpleCUBLAS example? Thanks!

The problem lies in the improper driver. After installing version 186.18(downloaded from http://www.laptopvideo2go.com/), it passed.
