I've just put together my new build with what I thought were 100% compatible parts but I can't boot with the graphics card in.
The main bits are:
Gigabyte ga-z77x-ud5h - latest bios
Gigabyte GeForce GTX 660 Windforce 2X NVIDIA Graphics Card - 2GB
I can boot, install, run mountain lion fine with the hd4000 graphics but as soon as the gtx660 gets involved nothing works.
I tried various boot flags and the nvidia drivers for mac but nothing helped.
Should I just send it back and get something others have reported works 100% ?
Any advice would be great, thanks.
