Yosemite self destructing partitions and GTS 450 drawing by scans

[SUCESS] Yosemite GA-P35C-DS3R and GTS 450

Cheers, I have the most bizarre thing happening to me, I install Yosemite with unibeast and all is partially ok, my hardware is as follows.
Gigabyte GA-P35C-DS3R
Gigabyte Nvidia GTS 450
Intel core 2 duo 2.66

I have my hardware DSDT that I used in Lion , Mountain Lion and Mavericks with no problems, just needed the GraphicsEnabler=Yes with PCIRootUID=1 flag and alc 889a extension and all worked well.

Installed Yosemite with success and no problems, booted to the system and created my user account, only the graphics are drawing by scans that go up the screen, you literally see the image drawing slowly upwards the screen. But as soon as user account is created and I restart the system I get a password asked, I log in and he gives me the color well and I hear the disk reading and it stays there. The worst part is as soon as I restart by reset switch the Yosemite partition and all other HFS partition mounted in all my older system disks are damaged.

One of the disks I managed to correct the errors with the unibeast USB pen but the second one I can't mount or fix anymore. Retried installing from beginning and installed Nvidia web driver and booted with nvda_drv=1 and the same, screen still draws by scans and after restart the partition gets damaged.

Anyone has a similar experience, any way to find what is going on? I never got a problem like this and can't figure out what is going on.

Thanks for any help in advance

Hey guys, no one with any info to share!? Or at least an idea?

cheers

managed to install all with success

updated my yosemite installer app to 10.10.1 and made a bootable usb pen with UniBeast 5.0.2
then followed the instructions from Ben74 here http://www.tonymacx86.com/mavericks-desktop-guides/113112-gigabyte-ga-p35-ds3r-gtx-460-success.html

booted with GraphicsEnabler=Yes PCIRootUID=1 installed and rebooted from the usb selecting my Yosemite HDD with -x GraphicsEnabler=Yes PCIRootUID=1

Then used MultiBeast Yosemite 7.1.1 with the no DSDT option. Checked the options for GraphicsEnabler set to yes, and PCIRootUID set to 1. Installed the nvidia web drivers for Yosemite 10.10.1 http://www.nvidia.com/download/driverResults.aspx/80070/en-us

edited my org.chameleon.Boot.plist and added the following
<key>Kernel Flags</key>
<string>nvda_drv=1</string>

rebooted, selected the nvidia driver and rerun multibeast selecting my dsdt with realtek lac 885/889a, elliotforcelegacyRTC, EvOreboot, FakeSMC, NullCPUPowerManagement, RealtekRTL81xx, Generate CPU States,GraphicsEnabler, Use KernelCache (and turned off PCI Root ID Fix), Mac Pro 3,1

Now all is working wonderfully except for iMessage and FaceTime

hope this helps someone
