I tried to install in Safe Mode.......did not work. tried downloading and installing a Sigmatel Driver from Dell.....same message in regular and safe mode. Help! Mike

 

Hi

Had not signed in so when I sent you my reply, asked to sign in and, when I signed in my message was gone so I will repeat.

Did as you suggested.
1. Installed Intel chip without problem & shows in Device Manager as installed.
2. Tried to install AC97 Audio Drivers and got the RUNDLL icon message 'Error loading STREAMCI.....specified module could not be found. When I hit 'OK' on RUNDLL icon. would not go away. Eventually, after repeatedly hitting 'ok' it disappeared & the installation progam itself indicated the drivers were installed. They are in the ADD/DELETE section of control panel as installed but are not in the Sound et,al., section of Device Manager.
3. Tried to install in safe mode with same results.
