wondering if its the mother board?

[troublemaker]

I recently build my own computer with an asus A8R32-mvp crossfire mobo and put an xfi soundcard that i got off ebay into it. Windows installed perfectly, all the updates and drivers for my other hardware installed and are running perfectly. However, i tried installing the drivers for my Xfi card and they would not install. Well they do install, but the wdm file doesn't. i have tried the newer drivers on creatives site to no avail and have done everything i can think of short of a complete reformat and reinstall. My comp recognizes the card and then searches for the drivers which i then give to it. It then finds the drivers and starts installing, However halfway through it stops and says error could not install hardware invalid data. It does precisely the same thing with the onboard audio. Would someone please tell me what is going on with this. Thanks in advance.

Have you disabled the on-board audio in BIOS before you try to install drivers for your sound card?

It could be a bad spot (weak sector) on the installation CD, I've seen that before. Try copying the installation CD to the hard drive first, then running it from there.

If that doesn't work, try putting the card in another slot.
