The GPU-Z shows CUDA is not running. That could be the problem. Also the ForceWare driver is 311 and current for the 760M is R331, not that an older version driver should make such a difference in running SM3. Go to the NVIDIA web site and update, just so that we can tick it off as not a driver version issue.
After updating the driver re-try the GPU-Z report and also the others especially the FurMark as that will use Shader Model 3.
If CUDA Computing is not ticked you may have to check with NVIDIA forums for reasons why no CUDA, or with your supplier support.
Try also directly via Windows Control Panel removing the NVIDIA drivers and re-installing 331. The update system is usually good, but sometimes it does tale a complete uninstall/re-install to get things working.
