The PC that I assembled at home has an Asus K8V SE Deluxe motherboard. This board has a build-in Promise Fasttrak 20378 SATA controller. The Vista default installation did not recognize this controller.
I did some googling and found this article that describes the problem. I tried the solutions that are suggest in the article, but with no success.
I am also having trouble getting Vista to recognize my external USB sound card (Creative Audigy 2 NX).
If someone has any idea on how to solve this, please let me know by dropping a comment.
