Hi guys please help me, I reformated my PC to windows xp service pack 2 after that it has no sounds.. device manager says that, it has question mark ? On multimedia audio controller and pci..

My mother board is Board: i440BX-I8671

Where to begin... you state you're looking for a sound card driver in the hard drive forum by posting motherboard and/or BIOS information.

Do you have a discrete sound card or is the audio adapter integrated on the motherboard?

If you have a discrete sound card, determine the brand and model and look for a driver for your specific operating system at the manufacturer's website.
If you have integrated audio, a Google for "i440BX-I8671" came up with many references to a Daewoo BIOS ID. Where are you getting that board info? That BIOS ID seems to be associated with a Daewoo CB648XBXC-00 board and others for which information also seems sparse or in languages I'm not fluent. Suggest you contact place of computer purchase or Daewoo International (http://www.daewoointernational.ca). Any additional info as to computer model or info directly off the motherboard would be helpful. Also, you may need to install a chipset driver first before installing any specific device drivers in order for everything to get recognized properly.
