no sound at all

[MyName]

Today, I stopped hearing any sounds in windows.
This happens both on my Creative X-Fi sound card and with onboard AC97
sound card. Windows detects both cards properly, it's just that I can't
hear any sound after I install the drivers (speakers are turned on, and
sounds aren't muted in windows). In addition, Windows won't even boot
after I install Creative sound card drivers (they boot normally if I
unplug the card and use onboard audio instead).
I don't think that this is a speaker problem since it also happens with
my old speakers and with my headset. Is it possible that I don't hear
any sound because something on my motherboard has failed? I think I
might have accidentaly fried something on it just before this started
appearing. I repeat - this happens both with onboard sound and PCI sound
card (I haven't tried plugging it in another PCI slot, nor know if this
would matter in my case). I'm need of help so I can know what part of my
computer I will have to replace. Except for sound, my system still works
fine.

-Thanks.

So you have onboard audio that requires its drivers to work and you also
have a Creative daughtercard that requires its own drivers to work. You
have a conflict in similar hardware both attempting to perform the same
function. Did you disable the onboard audio in the BIOS so you can
actually use the Creative daughtercard?

Not exactly, as I have unplugged the sound card before enabling onboard
audio, and disabled onboard audio in BIOS before installing PCI card - I
wasn't using both cards at the same time.

Did you disable the onboard audio in the BIOS so you can
actually use the Creative daughtercard?

See above.
