Asus Xonar Phoebus vanished (windows 8.1)

Level 7
Hi guys,

I have a Xonar Phoebus for a little over one year now and it always worked perfectly.

Couple of days ago i migrated to windows 8.1 from windows 8. The card was working fine but yesterday it decided to completely vanish from every place, including the device manager.

I downloaded the 8.1 x64 drivers but it says during the install that the card "doesn't exist".

I have all lights on on the card (the pink asus name and the red & green lights on the back).

I tried moving the card to another PCI-E port but no luck.

I'd have tested it on another computer but none of these have a free 6 pin power slot, unfortunately (modular power supply and international relocation made the extra cables vanish).

Are you aware of issued linked with the card vanishing for 8.1, even if u have official drivers for it ?

Sounds like a Windows issue - possibly from the migration. You might need to resinstall the OS. These things can be prone to problems like this.

Known problem with migration. Check your other drivers, some of them might have disappeared as well.

Hm Tried with drivers as old as the first on win7, no go 😞 everytime it can't detect the card. I guess only a full reinstall of windows can fix it, which is a chore.
