I am using Linux, but will try to point you in the right direction. To access CUDA functions PyCUDA has some part in C which is called from Python and calls appropriate CUDA functions. This C code during PyCUDA compilation is put into one library (DLL on Windows, SO on Linux) and is accessed by PyCUDA using pycuda._driver (line from pycuda._driver import *). It looks like in your case Python interpreter cannot find this DLL. Check if you have installed PyCUDA into directory present in PYTHONPATH - if not, either install it into appropriate directory, or add PyCUDA installation directory to PYTHONPATH. Another source of problems can be trying to run programs from PYCUDA source tree. This tree contains "pycuda" directory, but this directory does not contain DLL (which is build in different place). In result Python finds some parts of PyCUDA but not other - and you have result similar to yours.
