I have just finished reformatting my PC for the first time and wonder if anyone could help me with a query. I have a Philips Sonic Edge Soundcard installed in my PC. The onboard AC'97 sound that came with my PC originally is switched off in BIOS as per Philips Installation instructions for Sonic Edge. When I was reinstalling the VIA drivers etc from the Motherboard installation disc I noticed that the C-Drive drivers for the AC'97 unit were also on it. As the on board sound is switched off I chose not to install these for the time being but would like a confirmation from one of you experts that this was the right thing to do?.
