How I can reinstall an audio driver?

I reformatted – Windows XP Home – now "no audio device displayed in the system. "I tried to download the driver – download – reset -" This system is not compatible with the driver you are trying to install. " Windows XP was already installed when I bought the equipment I have no driver disk. It is an Intel P4 motherboard 845Glad; AC 97 SigmaTel – i tried installing the driver is an audio SigmaTel High Definition. Why not support my system? * The only change made to my computer before reformatting a PCI card installed. I do not know what to try next!

Intel 845GLAD must have SoundMax audio driver can be downloaded from the Internet and install it. It will work for you.
