Problem with Direct3D

I recently purchased he Dell Studio XPS 1340. After doing a fresh install and installing the laptop drivers etc, the action center had a pop-up saying i should download this driver from the nvidia site, and i clicked the link and the download started automatically. Earlier today when i was trying to set a screen saver i noticed that it said Direct3D was not enabled, upon further research i went to DXDIAG and noticed that it said out of the 3 DirectX features none of the features were available. I don't know if the drivers are/were installed correctly or perhaps there is something i have not yet installed, or perhaps there is something i'm comepletely off about. If anyone could offer up some information regarding possible issues, please let me know! And if someone knew how to solve this problem then that would be even better! Thanks in advance.
