One is an Audigy... the other is just a SB 5.1 card. Both are PCI.
I've also tried the Audigy card with an external USB card... either way Windows just ends up in a reboot loop after a restart.
Trying to do a fresh install of XP now.. however I don't think I'll have much luck since I've lost the licence key (yes, wasn't stuck to the PC... stupid). All else fails I will load the image of the drive done by Acronis, back to the HD and give up. :)
Just curious as if anyone has any ideas about the soundcards. I was using the built in HD sound but that appears to glitch/pop when lots of activity happening. MB is an ASUS M2A-VM
