First thing to know is that upgrading from Win 8 to 8.1 destroys the Phoebus driver install. There is no recovery for it. Some say they get lucky, but many of aren't able to fix it by normal means. So this leaves one option; erase and reinstall!
I don't mind reinstalling my OS. But I couldn't even get my OS to reset with the amount of errors that the Phoebus drivers were displaying. Microsoft was nice enough to spend 3 hours this morning walking me through how to reinstall their Upgrade version of Win 8.1 without my Win 7 discs. Granted most of it was them trying to find and verify my key from the Windows Store, but hey whatever works.
🙂First thing to do is backup your data that you want to keep. Songs, files, documents, save games, Japanese pron, etc.
Read this little
gem of a guide on Windows 8.
Using the guide I was able to find this
download for Windows 8 that allows you to completely erase your old installation and start over again. Make sure you choose the correct installer. If you choose 8.1, but own a 8.0 key it's going to tell you wrong key. Yes, you would think that the same key would work for both, but it doesn't.
Let Windows erase your Windows 8 install and start over anew. After you have 8.0 on your computer and installed you need to upgrade it to 8.1. I had to run Windows Update and update 8.0 until 8.1 Pro showed up in the Windows Store as a free upgrade. The 8.1 upgrade will be the first item you see in the Windows Store on your PC.
Open Control Panel and check for updates again. After everything is up to date, reinstall the Phoebus drivers. Everything will go as well as before. You should have zero issues getting them to install. Everything that was broken in Win 8.0 is still broken in 8.1, so don't get your hopes up.
I hope this helps some of the people who just can't get their cards working. Maybe Asus will send us a new driver. Sure would be nice. But if they don't at least you can get it back to it's prior functionality.
