I recently decided to upgrade my on-board sound to a fully fledged sound card. Well that was a mistake... Motherboard: Gigabyte GA-EP35-DS4 Bios version: F5 I bought an Asus Xonar DX and happily fitted it. Only windows didn't see it, and after a little exploration I noticed that the bios wasn't seeing the card at all, not even an "unknown" card listed in a slot. Not to be daunted, I assumed the card was FUBAR, but before I went off to start screaming at ASUS for a replacement, I thought I had better make sure it was the card. So I went and forked out more cash on a Creative X-Fi Titanium. Still no joy. Help?
