Well, technically, there is something wrong with the card. :)
It is a card not supported by the OS. :)
But in all seriousness, doing a google search, I found this with regards to the 7600GT Card and Direct X:
Is Nvidia 7600 GT direct x 10 compatible? - Yahoo! Answers
While Wikipedia has the following entry:
Windows Aero - Wikipedia, the free encyclopedia
I do not believe the Aero is Direct X 9 supportable... As there are mentions with performance issues with it on Legacy Direct X 9 cards. There is also an blog here where they think Win 7 Aero is leaning more towards Direct X 10.1 capable cards or at least, for performance.
Windows 7 Aero to take advantage of DirectX 10.1 ... where will this leave NVIDIA | ZDNet
