Samples fail with 9400GT GPU. What is wrong with my config?

I installed nvdrivers_2.3_winvista_32_190.89_general.exe driver, OS is Vista x86.
When trying to run samples from SDK I get application crashes.
For example:
S:\OpenCL\oclBandwidthTest.exe Starting…

Running on…

Device GeForce 9400 GT
Quick Mode
(and crash after)

And another:
oclDeviceQuery.exe Starting…

OpenCL SW Info:

then crash.
What is wrong and what should be installed on host beside OpenCL-compatible driver to run samples?

[Solved, these samples was compiled with CUDA SDK 3.0 beta while driver for CUDA SDK 2.3b was used]
