Gigabyte GA Z68A-D3H-B3 1155 Yosemite

[MacAspirer]

Dear Forum Members, Thank you very much for providing latest software updates to non apple products, i am enjoying hackintosh for last two to three years, started with Lion, Mountain Lion and Mavericks. I have updated to Yosemite but I have following difficulties hopefully the forum members help me regarding this,
My configuration is as follows.
Motherboard is Gigabyte GA Z68A-D3H-B3 1155 socket rev 1.3
CPU i3 2105 Sandybridge processor.
8GB RAM 2GBX2 gas kills rip jaws 240 pin DDR3 1600 pc312800,
4GB CORSAIR Vengeance 240 pin DDR3 1600 PC3 12800
EVGA GT 640 2 GB RAM

I am able to boot from SSD I have installed yosemite.
When I start computer it showing CMOS reset error, please see the attached file.
After Apple logo and the loading bar, suddenly monitor is shutting off, because it is not getting any input I am not sure why this happening. I am also attaching my multibeast settings.

When I take the GT 640 graphics card out, I am still getting the error for CMOS, but some times I am able to go to the login screen after the apple logo and loading bar, sometimes not. Airplay is working just with the inbuilt sandybridge gpu, but if I attach GT 640 the airplay mirrorring not working.

I request the forum members to help me.
