Won't boot past the startup screen (no login screen)

I use Windows 7 Ultimate 64-bit with a GTX Titan. Triple displays.

I was playing a game and got a weird graphical crash during a cutscene. All three monitors went blank. (each a different color which was odd) I had to forcefully shut down the computer as I was never able to move past this. It didn't seem like I was able to interact with the computer at all with keypresses.

So after rebooting, the computer was ok until I tried to play the game again. Once again, during the cutscene, the same thing happened. On the third time, when I went to boot the computer up, during bootup, it would do everything normally, including the Windows startup animation. But then a blank screen. It never went to the login prompt. And trying to type my password didn't help.

I shut down and went into safe mode. My files and drives were all fine. I tried uninstalling my graphics driver, then when I would reboot and reinstall my nvidia drivers, I'd get the same issue where it was a blank screen instead of the login screen.

To rule out any issues with the monitors, I unplugged two of them, but then when I booted up after a hard shut down, rather than having the option to enter safe mode, I only got the options to start normally (which fails) and windows repair, which just goes through a long drawn out repair and fixes nothing.

I plugged the monitors back in and am still unable to even get the safe mode option anymore.

Your disk may be dying.
Lets do some tests
Boot from win 7 installation disk, go to repair and launch a CMD window. Type:
1)chkdsk c: /f
Pay attention on the results, specially bad clusters or bad blocks.

2) Open a CMD window and type:
sfc / scannow

"This version of System Recovery Options is not compatible with the version of windows you are trying to repair. Try using a recovery disc that is compatible with this version of windows."

Which I don't understand because I am using the same disc I used to install Windows on this machine in the first place. Windows 7 64-bit Ultimate.

Did you do the disk an system check as instructed on post #2?

Well I wasn't able to get that far. I have no way of running a chkdsk without getting past the repair option in the Windows startup when I boot to the disc.

I can post some pictures of what I see when I get home tonight. But basically, it boots to the disc and starts an installation. Right after the first prompt I have a "repair" option which results in the error I mentioned in post #3. That's as far as I'm able to get.

Are you booting the installation disk of the same version it is installed (32 or 64 bits)?
To do a repair you can use any Win 7 disk (home, HP, Pro or ultimate) as long it is same version it is installed (32 or 64 bits).
Did you ever upgrade to win 10 and roll back to Win 7?
