Hi guys, I need desperate help. This computer had sound with no problem until I tried to install a new yamaha soundcard that i bought from the computer store. Upon install i got a few blue screens of death and then the sound went out completely. Thought it was the card so i went and got a used sb live card that i have had no response whatsoever from. At this point my sound manager is all greyed out so i cant select anything and my diaxdiag says there is no sound card installed?
Can someone please help me?
I think i need to reinstall the mb soundcard as well as the crystal soundfusion, but i dont know which i need.

We don't either since you didn't say what motherboard you have. "Intel Celeron-A 400 mhz" is not a motherboard.

Is this mb a retail motherboard or is it OEM (ie: did it come pre-installed in a pc system? If so, what system?)
