Absolutely no help from Zotac :-

Unfortunately we only provide support for Windows XP, Vista, and 7 operating systems.

I can suggest searching through different forums on the web for any support regarding you situation

We apologize for the inconvenience

Please let us know if you have any other questions

...

You wouldn't think it too much to ask for a hardware company to support it's hardware and leave Windows support to Microsoft. :-(
