It was fixed w/ 326.01 win 8.1, no blank screen with this version either...there's no VBIOS update from alienware, probably nvidia decided to fix it through drives due to win 8.1 preview release.

Try to flash svl7's VBIOS, download Download NVFlash 5.128.0.1 | techPowerUp then go here http://forum.techinferno.com/general-notebook-discussions/2166-%5Bguide%5D-nvidia-vbios-flashing.html Rename the .rom file to '780M' (8 characters limit). Backup: nvflash -b backup.rom VBIOS flash: nvflash -6 780M.rom Type twice 'y' to override PCI mismatches.

Supported card still better disable driver signing, safe mode option only when pressing F8 like win Win 7; useful for testing.

Probably driver signing was disabled cmd admin type "bcdedit /enum" look for windows boot loader results, better to leave F8 safe boot option enabled.

It seems good, then it's probably VBIOS related as you've tried everything else http://forum.techinferno.com/general-notebook-discussions/1847-nvidia-kepler-vbios-mods-overclocking-editions-modified-clocks-voltage-tweaks-227.html

It shows both GPUs being tested, disable IGP then run test; always thinking 120Hz.
