I cant find drivers for an Intel based motherboards which has 845g chipset family. And thats all i know about it. Please someone help!

Without much more detail - or a few more letters anyway, there's not a whole lot we can do. The drivers page for this is:
support.intel.com
You're just going to have to try different Audio drivers, until one works. Or open her up & see what's there.

thank u verymuch it uses 97ac the mother board doesnt say anything on any of its chips at all i tried to find out through the manual but that only tells you the graphic drivers needed and nothing about sound cards.

The lesson of the Day: build your computers dont buy them from stores but build them yourself.

Dude... You are so right. Here's a lesson for tomorrow: When purchasing a used computer from another person, look at its guts to make sure you're not being scroood... :-)
