Hi, the other day installed mavericks as usual, everything went fine.
It worked a few days, and when i wanted to boot it again i got a grey screen after the apple logo. It doesn't worried me a lot because i get used to have a crash on my hackintosh everytime a month..
So, i decided to install it again, and after the install, again, the same problem.
I tried with so many bootflags, even -v, but the verbose mode it's ok, and then it goes to the grey screen, so in the verbose mode i don't see any errors.
PS: Also, i tried to install Mountain Lion, and i can't get video signal after install, the monitor (Screen) goes to stand by mode with my GTX 760.
Any info will be appreciated.
