Hackintosh problems post-installation

So I have 3 main problems, that bother me a lot.

The First problem is that i installed macOS Sierra, the Nvidia WebDrivers and the CUDA Drivers, I am graphic accelerated but the problem is that AS SOON as I plug the second monitor(be it the HDMI or the DVI adapted VGA one) into the 980, Sierra crashes to black screen and goes to bios.

The Second problem is the I CANNOT boot Sierra without the USB drive, I can't see the drive into the UEFI, no matter what, clover is into the drive, I don't know how to do, searched millions of posts, I really want to boot to clover easly so I can choose between windows and Sierra.

The Third problem is that the UEFI has become so slow since I started resetting it constantly after I installed Sierra(to get to clover) for no reason at all, usually it took from 8 to 15 seconds to get me to logged windows, now it stays on the "ASUS"(Z97) logo for about 30-45 seconds, with me spamming F2 to get into the bios, I noticed that if I don't get into the bios the UEFI doesn't boot at all, it's stuck on the ASUS logo, doesn't do anything, any help?
