did you check with the pc running as it is now that the motherboard falling over to onboard video port???
is the video cable on the right video port. did you install mvp software that bonds an ipgpu and gpu together??? as the software is buggy. on the video card is all the power plugs connected.

seems like the problem is with the latest nvidia driver. if you have just installed it and also run a multi monitor env (its enough just to have an additional hdmi cable pluged in), the main screen (with the log on credentials) will not be displayed.
so, remove any additional video cables and leave only one...

I had a similar problem shortly after I first installed Windows 8. I re-installed at least twice to new hard drives and still would have Windows 8 looking like it was booting and then stall at a black screen.

Accidentally, I hit the scan button on my monitor and, magically, the monitor scan found the correct port with an active signal on the monitor. My computer has a dual port DVI output video card, which I use to drive two 24 inch HP multi-port monitors. What I came to understand, without knowing the cause, is that during a cold boot or a reboot Windows 8 would intermittently appear to be booting normally, but the monitors, which were showing the initial sequence correctly, would go black and the process would appear to have stalled. I initially had interpreted that as a failed Windows 8 installation.

What actually appears to have happened is that Windows 8 would be booting normally and the monitor, which initially was showing the boot activity, would become selected to a different port with no activity and which was, therefore, displaying a black screen. I never determine the cause, but the solution was simple enough, even if annoying, to press the monitor’s scan button and let it find the active port.

Gabriel Tatu's solution was spot on for me. Removed any additional video cables. Sucks to not have multiple monitors but that's Windows for you. Prior to this I had tried restarting it about 10 times and a bunch of other BIOS stuff.
