I'm not sure what being old or young has to with anything. Being older or younger doesn't make anyone wiser or less experienced with these issues. This isn't a contest about how birthday's either one of us has seen. The fact is - if you have a basic problem, alla no sound coming from a system, the proper next step is not to go straight to uninstalling the sound card and all of its drivers. It's absurd to troubleshoot in that fashion. When my computer monitor does not display the correct resolution would you suggest uninstalling the graphics card? I would certaintly hope not.
Again, you said it yourself. Sound cards rarely go out. So uninstalling the drivers for it without figuring out if you have the ability to properly reinstall it is pointless. That's taking zero steps forward and two steps back.
