DSDT Request ASRock Z77M

Hi to all! It seems there is a major problem with this mobo when used with an Nvidia Fermi graphic card (maybe a tension problem) that cause an infinite black screen during the boot... A correct DSDT should resolve this issue! Can someone help me?
Thanks!

Andrew, there is nothing wrong with that motherboard. You need to boot with -v and see where its stopping.

Have you flashed the BIOS?

Try taking out the GPU and get the onboard graphics working later you sort the GPU issue.

i already have flashed the bios and without the gpu everything works fine! with the gtx 480 afer the inital loading i get a black screen! in verbose mod everything goes well untill when it should load the desktop, whitout giving any warning. the first lines of the loading tell that the gpu is nicely recognized, with the right name and the correct ammount of ram. :/ infact with mountain lion 10.8.2 all the fermi gpu should be automatically recognized!
any solution?
thanks for the assistence
