I have a Crystal Semiconductor cs4280 on board sound chip. My computer freezes constantly because there isn't an updated driver for directx 8.0. Whenever I disable the soundcard, everything works fine. I have been to crystal's website, but the only driver there is for directx 7.0. Where can download an updated driver or even directx 7.0? Is there a way to uninstall directx 8.0 without reformatting? Any help is appreciated.
