I have recently reinstalled Windows XP on my eMachines computer and I'm having some trouble with my drivers. First and foremost, I have no sound. When I look under Sound in the Device Manager, I only see: Audio Codecs Legacy Audio Drivers Legacy Video Capture Devices Media Control Devices Video Codecs I have tried installing every single driver on the emachines website for my model (W6409), but nothing has worked. So, any ideas? Also, under Other Devices, I have a ? with an ! on it for: PCI Device SM Bus Controller Help please!
