Can't pass the login screen. Endless loading

[cmn699]

I don't know what other problems could be still lurking inside your /System/Library/Extensions folder to prevent your Installed latest nVidia Webdriver to be loaded by the bootloader after the corrected .plist.

Because of your Numerous troubleshoots and shut down and reboot routines for the past several days, if your BIOS Settings might have changed from PCIe [PGD] to IGFX [IGD] should be verified. If I were you, on this reboot, I will enter BIOS Settings and make sure PCIE is my Display Video option not IGFX.

Good luck

I corrected the .plist and when I try to boot with -v -x it writes IMG_0227 and then my monitor turns off and writes NO SIGNAL
If I try to boot with nvda_drv=1 or nv_disable=1 it says Missing bluetooth controller transport and stops

Just try booting with :
-v -x -f nvda-drv=1and see if you can boot.
If you can then you may have to edit plist and remove GE=Yes and IGPE=No and just add nvda-drv=1 and see if it will boot

Whatever error you can see, please take legible photo >upload image, so we can look for clues.
Thank you

I also looked at your BIOS image showing you had selected PCIe. I

want to know whether it had changed and you had to select again. You did not say anything about that image. If it had changed from your previous settings , then there is a good chance Vt-d must have gone back to its default . If the default is Enabled, then we can have problem from that too.

If you see one setting has changed, it is imperative to check all settings.
I just thought of making that very clear.

To sum up:

In order to avoid {NO SIGNAL} error I need to boot with PCIRootUID=0
My graphics card boots only with -v -f nvda_drv=1 (and it's recognised in About My Mac) BUT it still doesn't work
Nvidia Driver Manager says I need to reinstall driver and reboot but when I reinstall and reboot it says the same.
Even wallpapers are not shown but I can change them by randomly clicking in the white field, to say nothing of numerous lags and freezes.
So, I failed to start the video card fully and also beachball problem appears at times.

Anyway, I'm intensely grateful to you for helping me so many days. I need OS X for my work and thanks to you I'm able to do it. I'll try to make the video card work at last tomorrow. If I fail, please help me to carry it through.
Thanks once again, cmn699. You the real MVP
