I have an older computer running windows xp pro sp2. The on-board sound on my mobo is automatically installed during windows install. Unfortunately, the windows driver doesn't work. I have the driver that I know works from biostar (mobo manufacturer) but if I go into device manager and click update driver, it wont let me because my driver is not digitally signed. So I go into the add new hardware wizard, go all the way to the bottom of the current hardware list and click add new. I click have disk, and it installs the driver I choose (the right one) but now, the device I just installed can't start because the windows drivers and still installed on the sound device. If I uninstall the windows drivers now, I still can't get the device to start. If I uninstall the windows driver before I do that new hardware trick, then windows finds the uninstalled windows driver and reinstalls it before I can do anything. By the way the error code I'm getting with the new driver installed is 'Code 10, Device cannot start'. Is there any way to turn off automatic installation of hardware or anything I can do? This is very frustrating. Thank you.
