GeForce 105M CUDA not detected as videocard

I have an ACER ASPIRE 5738ZG with Nvidia G105M CUDA. The card only appears to be detected as monitor adapter and HD sound card, but I cant see it as videocard.
I have the drivers updated from Acer support but are VGA Drivers. I think something is not going right.
See the attached screening and let me know what it can be.
Thank you.
