I am having problems - NO sound XP-onBoard sound Card
The device manager gives me a yellow "!" on Microsoft Kernal System Audio
Device
with the error message "Windows cannot load the device driver for this
hardware because there is a duplicate device already running in the system.
(Code 42)"
No trouble shooting help is avialable. Any ideas how I get my sound back?

Have you seen the following article in the Microsoft Knowledge Base?
https://mvp.support.microsoft.com/default.aspx?scid=kb;en-us;310123

Try uninstalling the problem device and rebooting the computer. The
problem may be resolved when it reinstalls.

Are there any other entries in Device Manager with error or conflict
flags? These also need to be checked out and resolved as they may be
related.

Also are there any entries in the "Other Devices" category? These
need to be removed/uninstalled.

With older versions of Windows it was sometimes necessary to boot into
Safe Mode and then check in Device Manager as sometimes incorrectly or
partially installed devices would only should up then. Haven't
encountered this as yet with Windows XP but it might happen.

Good luck

Code 42
[[Windows cannot load the device driver for this hardware because there is a
duplicate device already running in the system. (Code 42)

Recommended resolution
A duplicate device was detected. This error occurs when a bus driver
incorrectly creates two identically named children (bus driver error), or
when a device with a serial number is discovered in a new location before it
is removed from the old location.

Restart the computer.

On the General Properties tab of the device, click Troubleshoot to start the
Troubleshooting Wizard. ]]
