[half-sloved] I don't know how to go on -.-

So hello community,

I've installed hackintosh on my pc an half a year ago. Since then he worked fine, but he just started with rboot (what wasn't a problem). But now I upgraded my PC with a new motherboard (AsRock z68 extreme 4), CPU (i5 2500k) and new RAM but that isn't so important... I booted my PC with rboot like before but it didn't work (what a miracle -.-) but then it tried to start in -x mode and it worked... then i tried to reinstall OSX but the CD didn't boot up to the screen so maybe I just need a dsdt but with no expierence with it.

Does anybody know how I get back in normal mode?

Maybe my prePC infos are important:
AsRock ConRoe-1333 DVI-H
E6600 2,4 GHz
also there was no dsdt work done for that board only MB

Also a great new year

so i got it worked without x mode, and after reading some other topics I thought it would be great to install 1.7.0 (because of HD3000).
caused of this installtion only x mode work again. By normally starting with rboot I get the grey screen. -.-
