Have xonar dx in xfx 680i sli mobo pci-e slot and no recognition. I have the floppy power cable connected. I've even tried putting the xonar in the pci-e 16x w/o recognition. I've also tried going to the asus site and downloading latest driver w/o success. I tried updating bios to p32 version(latest), but computer froze on verifying dmi data pool. Please help, I really want to be able to use my xonar dx card.
