Hey, I have just formatted my computer and now I don't have any sound. I downloaded a specific .inf file for my motherboard off of the Elite ECS site and added it with the "Sounds and Audio Devices" in control panel by clicking "Add New Hardware." It was put on the list successfully, but it has a yellow "!" beside its icon. When I click on it to get more details about it, it says "This device is not working properly because Windows cannot load the drivers required for this device (Code 31)." The .inf file I have is C-Media AC97 Audio Device. My other computer had this same problem and was fixed by my uncle, but I forget what he did to fix it, (I think he uninstalled all of the unnecesary devices under the sounds, etc.) If anyone knows how to fix this problem, please post. Thanks in advance, Jon.
