Computer will not boot past 'starting windows'

[Coneitic]

I came to my computer and the screen looked pixelated, I manually restarted my computer and the fun started.

The computer boots up to 'starting windows' at which time it either restarts itself or it hangs at a black screen, never booting.

I can access safe mode with networking.

Things I have tried:
Reinstalling Nvidia drivers manually and using specific programs.
Reformating 3x over.
Trying earlier versions of drivers.
Putting video card in another computer and receiving same results.
Checked the ntbtlog.txt that shows no nvidia drivers are able to load.
Moving PCI-E slots and using other psu cords.
Trying different versions of windows (home,ultimate,etc)
Removing video card, removing drivers, re installing drivers and reinserting video card.
After reformating, i updated windows and ever driver before the nvidia drivers.
Removed CMOS for a few minutes.


The second computer is has an older PSU so I am not sure if it is the PSU that can no longer power the video card or the card itself. The PSU i was using is a 850w, the second computer giving the same issue has a 650w.

I can not pinpoit what caused this only that my computer was running fine, left for a few hours, came back and it had restarted and was pixelated but i could still see the log in screen.

I had this same issue about a month ago, with an AMD Radeon GPU. After a ton of research and trouble shooting, I decided the most likely issue was that my power supply unit was not supplying enough power to the graphics card to allow it to boot correctly. Uninstalling the AMD drivers completely so that my laptop used the on board Intel GPU instead allowed the computer to boot past "Starting Windows" and complete start up. If you have that as an option, I suggest trying it. I had full functionality of my laptop after updating the Intel driver (until a recent hardware change that ruined everything) so I didn't miss the AMD at all.

You don't see the logon screen? Disk light keeps flashing? Black screen with mouse pointer? If so...can you move mouse pointer? Textcursor... is it blinking?

Putting video card in another computer and receiving same results.

You mean that if you install the video card in another computer.... that other computer has same problems.... correct?
