Can't install audio drivers, could it mean dead card?

I assembled a new pc earlier today and have been trying for hours to install the realtek HD audio drivers with no luck. It goes all the way untill the very end of the installation and then says "audio driver failure 0x000000ff".

I've tried the drivers that came on the CD together with the motherboard (ASRock h110m-hg4) and also tried downloading the newest ones from the ASRock website

My question is just the following: Is it possible that I got a new mobo with a dead audio card?

I just kinda want a yes or no answer to that. I've been thinking it might just be dead but I don't really know if being unable to install a driver could actually mean the hardware is not working or is it just software related.

Windows 7 x64 by the way
