Intel motherboard 945 drivers free download

Your best bet is to find out what audio chip it uses then go to the site for that chip. It's probably a REALTEK chip (or you may be out of luck).

If so http://www.realtek.com.tw/downloads/

Make sure it's the correct version.

You should ALSO go into your Device Manager to see if anything else is missing or in conflict.

*You may also go to the motherboard site and look for drivers but I don't know the exact model beyond "Intel 945"

However:

If you have other Intel chips (main chipset) that are not up to date, there is a link on here to look for updates.

i can't read you post, stop SHOUTING!!!

Need more info. Can get the sound card info when the only data you posted is the motherboard chipset. What the model of system or the motherboard?
