Problem with NVidia gts 450 gpu.

I can boot only with flags nv_disable=1 GraphicsEnabler=No IGPEnabler=No -f -v. But system is so laggy.. When I am booting without these flags, my monitor goes to sleep. How can i fix it?

NVidia gts 450

Intel core i3-2100

4gb ram

ASRock H61MVS

Do a fresh install, then install nvidia web drivers and see how you go. Might need to find a beta driver

This problem appeared in the yosemite-zone installer. Graphics was very laggy. Also i've tried to install El Capitan with clover bootloader, but I wasn't able to boot in the installer(because of the same problem: my monitor was sleeping. I didn't try flags, because it is useless to install EC if problem is still here.). Im using DVI to VGA adapter to connect my monitor. Also in my gpu is micro hdmi port, but i dont have cable :(. Which drivers should i try?
