Old Intel Mobo No Sound Driver For Win 7

Howdy ... working on a friend's computer that has an old Intel D845GRG mobo. The hard drive died and I replaced it and installed Win7 instead of XP on the new drive. She has a problem seeing and needs win 7 for voice recognition. The mobo drivers only support as far as XP at the intel support site. I don't have any sound and I need to install a driver so I can get sound from the mobo. Is there a way to get a compatible driver? Or do I have to get a sound card that supports win 7? Thank you for your reading my post.

 

This is the better option.

But first try one of these driver updaters.
