It's an Intel D845GEBV2 which Intel say they no longer support, your drivers are here, download 5+7 and save both to a file on your computer ( where you can find them ) name the file MoBo Drivers, then install 5. Audio AC'97 and see if that works, if it does'nt you will need to install 7 first it's the chipset driver then the audio driver again.
Create a System Restore point before each install just in case http://downloadfinder.intel.com/scri...5&submit=Go%21
