Blank screen

[AsierGarcia]

Hi all,
We built a Mackintosh with Yosemite 3 months ago following Installation Guide with Unibeast and Chameleon. It went smooth and it has been running until today nicely.
However, today starting up after an itunes update to v12.12 the logo run a third of the bar and the screen suddenly disconnected and became black.
First, we thought of a BIOS setting changing on its own and after checking it up, we did't see any change.
Then we have been struggling for several hours reading threads in the forum and trying to start with all sort of combinations with different flags including -x -v -f GraphicsEnabler=No npci=0x2000 config=null UseKernelCache=No/Yes kext-dev-mode=1 ... No combination has worked so far. Same result.
The built is:
Asus Sabertooth X79
Gigabyte GTX 770
Intel 4820K
32Gb RAM G.Skill
The org.chameleon.boot.plist that has been running nicely until today is attached.
Any clue on what's going on?
Regards,
Asier
