This is my problem. I purchased a Audigy2 sound card to replace my Audigy. So I installted the A2 card, installed the drivers and then I go to reboot and it hangs at the Windows Splash screen. I then go into safe mode and remove all the drivers with driver cleaner. Then start the whole thing over again. It does it again. Then I change pci slots and go through it over again, still nothing. I tried another pCI and still nothing. I do notice that it stalls out a the Driver portion of the installation. So I take it to my other Mobo (non nforce) and it install without a hitch. So I RMA the Sound card.. thinking maybe the sound card didn't like the mobo. So I just get my RMA A2 today, slap that bad boy in and it doesn't load up the drivers I reboot and it hangs at the Windows splash screen like my original. So I slap in my SBLive everything goes wells. I am able to boot into windows and get sound, I do this to all my empty PCI slots. No installation problems at all. I then do the same with my A1 card with a flawless installation. Then I go and slap my A2 card back in and it doesn't want to install. I do this after a reformat of my HDD. Does anyone have a clue of what could be causing this. Cause I took this card and installed on my other computers and it installed without a problem. Should I RMA My mobo? I also set everything back to default and tried and still no luck.
