Having re-formatted and re-installed Windows, I now find that windows looks forCS4237B for my sound card, but labels it with a ? and ! mark in coputer properties. I also have no sound. I cannot find a FCC ID number on my sound card, and I cannot identify a sound chip anywhere. On the card that my audio sockets attach is FLORENCE AUDIO RISER CARD TGS-90371 with a SN T2378-WRI-00896. Help, please!!!
