I did a clean install of windows xp pro and now no sound. I have an Asus p5p800-vm motherboard and American Megatrenda bios 0502 5/26/2006. I have the video and audio drivers installed but it says no audio device installed. Also I can't load some video games. I have checked volume, mute, device manager, sounds and audio devices in the control panel. I have been in the bios and reset to default settings, I have reloaded drivers. Has anyone got any other sugestions?
