Yosemite is Boot finish but blackscreen

Recommended Posts

after the hackintosh zone logo with the loading bar my monitor shows "no signal" message and everything goes black. but when I press some of the key there's have a sound responded... 

sometime I can boot as normal, sometime its goes like I said. I've tried  nv_disable=1 its works but very bad graphic. and i've tried -v its also works like normally boot but I'm not sure this will always work.

 

any thought or solutions? 

 

Intel I7 2600k

8GB DDR3 (2*4)

Asus P8Z77-V

Asus Geforce GTX 590

SSD 128GB

 

ps1. everything works fine when I was used Maverick.

ps2. Is there anyway to set clover countdown and boot like Maverick version?

ps3. sorry for my english, its wasn't my main language.

 

Thanks for help.

Did this card work with Mavericks 10.9.X ??? This is a card with twin GPU's right? this may be a problematic card to use in Mac OS X but it seems that some one got this working in Mavericks perhaps same solution works in Yosemite http://www.hackintoshosx.com/file/3695-nvidia-geforce-gtx-590/
