Adding a soundcard when on-board sound is already installed

My motherboard has on-board sound, but now I want to add a soundcard instead.  Should I just disable the drivers for the on-board sound?  If I uninstall them, they just get reinstalled when Windoze starts because the on-board hardware is re-detected.   Same thing with the #2 LAN port that I'm not using.  It installs it whether you want it or not, and if you just don't do anything it's constantly telling you that a network cable is unplugged.  So I disabled it to shut it up.

Disable them in the BIOS, and Windows won't even know that they exist.

You should go into BIOS/SETUP/CMOS and disable the hardware there.  Then Windows won't detect it.

Disabling the drivers isn't good enough - what you need to do is to actually disable the device in the BIOS.  (The BIOS is where you go when you enter "SETUP" mode when the system initially boots--  usually entered with something like DEL key, or F2, or.... just follow the on-screen prompt).

So long as the device "exists", Windows will keep trying to install drivers for it, unless as you did, you "disable" the device in the system properties section.     When you DISABLE the device in the computer's BIOS, the Windows will NOT see it anymore, and you will also avoid having those ugly red X's in the devices section of your system.

Disabling the device in the BIOS is also cleaner, as you won't end up with (POTENTIAL) irq conflicts and such due to multiple devices being found.

When you're in the BIOS setup area, look for "Onboard devices" or something similar.

Should I first remove the driver, which is already installed, then restart and go into bios to disable, or does it matter?

It doesn't matter - the driver won't be used if the BIOS doesn't have the device turned on.

All you need to do is disable the device in your BIOS.    Yes, for cleanliness and pureness you can remove the driver, but it doesn't matter one way or another.    All it means is a few extra (unused) files in your windows system directories.  

If you want to be wholly clean about it, do it this way:

* Remove drivers
* Shut down
* Power on, enter BIOS setup
* Disable the internal sound device
* Continue boot into windows
