If you get error like "'fxc.exe' is not recognized as an internal or external command," when compiling CUDA sample, it is because the DirectX utilities is not found in your PATH, set it and rebuild the project.
Remember to install DirectX SDK before.
You might also need to setup include and library folder point to DirectX SDK folder.

Install CUDA display driver on U45J series
For my Geforce 310M graphics card, when I do install the CUDA official driver, it told me that the driver is not supported. Here is how to update it.
1) Download CUDA driver file from Nvidia webpage http://www.nvidia.com
2) From the Start Menu in Windows, go to run and type dxdiag. Once the window appears, on bottom right hand side there is an option to "Save All Information". Save this information on your Desktop. It will save a .txt file to your desktop.
3) Within this text, file search for the section "NVIDIA GeForce 310M". You only need to use a certain piece of the Device and Subsystem ID such as " PCI\VEN_10DE&DEV_0A70&SUBSYS_12D21043&REV_A2\4&179FD7D4&0&0008" from my base U45J laptop. This will be important in the next step.
4) Now you will need a tool like WinRar or WinZip to extract the files from the Nvidia driver executable. Once you have WinRar or similar installed, you can right on the Nvidia driver executable and choose extract.
5) Within the file folder extracted from the Nvidia driver executable, you will need to open the file nvam.inf, choose find and enter the "0A70.02". There are two instances to find. Once you have found the first, towards the end of the line you should see the text "PCI\VEN_10DE&", highlight all the text following this and paste the Device and Subsystem ID found earlier in Step 3. You should end up with something like “%NVIDIA_DEV.0A70.02% = Section077, PCI\VEN_10DE&DEV_0A70&SUBSYS_12D21043 ".
Make sure to do this for both instances.
6) Now you must uninstall the nvidia display driver from the control panel. Make sure to only uninstall the display driver as that is all you are updating.
7) Now you can reboot. Once your computer has restarted, within the file folder extracted from the Nvidia driver executable, you can simply double click the setup.exe, and your new driver will install.
Tips: Download the original NVIDIA driver from manufacture and then find the corresponding .inf file so that you will know which file to modify, in my case is from ASUS and they update the nvam.inf file, inside that file you'll also find the correct update inf for your driver, just copy & paste it into the official NVIDIA inf file.
