Ok so I have a Dell Dimension 4600c and I had to format and re-install Windows XP home Edition. I did so with the disks provided by Dell. When I had finished this the video card and sound device were malfunctioning. I had to use another disk provided by Dell to reinstall the video driver and now that works, but when I tried to reistall the sound driver I keep getting a error message that says I have no sound device installed. As far as I know the sound card is integrated into the motherboard. I opened the computer to upgrade the ram and saw only 1 open slot but I believe its for a video card upgrade, its a brown plastic slot. There are no other open slots that I can see. Everytime I try to use something with sound I get an error messsage saying that I have no sound device installed. Can someone help me? Or should I take it to a tech? Thanks in advanced for the help!
