Microsoft might have also broken alias updated something in Windows.
Considering Asus has dumped support of even lot newer cards and recently even lot more expensive ones wouldn't be surprise if they ended support for such old PCI card.
You could try UniXonar driver

Choosing anything from OS list just doesn't give any driver page...Is there anything on here of any help from the US

That's indeed the question...Why?
So any suggestions for a decent mid range sound card? I've tried installing drivers i found on other threads, but installation gives up on me....card must have died
This is going to sound really stupid but have you tried changing the install folder? I found for some strange reason that Asus audio stuff often will not install to odd level folders.
There's usually custom install setting which allows choosing directory if default installation doesn't allow changing it.How do I change it?
