GT 610 doesn't boot without nv_disable=1

Hi!

I just build my second hackintosh. I followed the installation guide and almost everything worked fin until I come to nvidia web drivers. I installed them and added nvd_drv=1, but it showed me spinning wheel. I can't boot without nv_disable=1 or -x.

Please help!
