I wiped the hard drive of a Latitude C400 laptop (Previously running Windows 2000 Pro) last Friday and installed Windows XP Pro instead.
I installed the sound driver (Crystal CS4205) which i obtained from the Dell website and it installed without any problems. It prompted me to reboot the laptop after installing the sound driver and on shutdown, I got the sound of windows shutting down. On booting up and going back into windows however, there's no sound. I've checked the sound driver in Device manager and it has the yellow exclamation mark next to it saying that the driver failed to load up.
I've uninstalled the driver and rebooted the laptop, the sound card is detected once it loads up windows and automatically installs the driver. Again, I'll have sound until the next time i reboot the laptop and then the sound driver will fail to load up again.
I've looked in Event Viewer but can't see anything that sheds light on why this is happening, i'd really appreciate any suggestions on how to troubleshoot this problem.
