I bought a PC(1) that had a creative sound card installed. I removed the card and put it in my other PC(2) now I cannot get the sound to work on PC(1) that had the creative sound card removed. When I go to Control Panel: Sound and Audio Devices everything is grayed out. I think I have to reinstall some driver but I have no idea what kind of motherboard it has. Is there anyway to find out what make and model motherboard you have using Windows, so I can find the proper drivers??
So you've removed the creative sound card from PC 1, but does PC 1 still have an audio device - did you insert a different sound card into PC 1, re-insert your creative sound card into PC 1 or are you trying to use onboard audio on the motherboard?
