Yeah it will just beep. But you could throw a stick in from your main if it's compatible.

Have you tried going into your nvidia control panel and adjust horizontal/vertical controls from there? What does that do? I suppose this may be driver related, worth a check. Have you tried wiping out the current install with Nv Cleaner and reinstalling newest ones from scratch? or just using the windows generic driver?

Okay so problem solved.

I disconnected my 5.1 from the computer and it went away. PSU problems?

Weird that it has never happened before.
