Sound just stopped for no reason?

I'm using a Creative AudioPCI ES1371 on a Windows XP Proffesional system with an AMD Athalon 2200+ chip. I've had this soundcard for ages and I've had no problem with it, but today for no reason that I can tell it suddenly refused to function. I uninstalled and reinstalled it in windows--no help. I then removed it from the PCI slot and put it in a diferent one, and then Windows recognized the card again, it shows up once more as functioning in Device Manager, but I still get no sound in anything.

I can't find any drivers for this card in WindowsXP, and I have no idea what to do now.

You may have to purchase a new sound card. Going by your post.
