What RAM are you using?
Other than that, I would pull out the card and boot without it. Plug your monitor into your motherboard. Check if it boots.
If it does - finish installing all drivers and updates then plug in your graphics card. Try booting through the graphics card. That's assuming you won't be using any of the Virtu MVP stuff. If you plan to then follow the directions for properly setting that up.
