Booting to Black Screen After Successful (?) Bootcamp Installation

Hi everyone, please have a look

2012 MBP

Latest version of OS X (updated then time machined before running bc assistant)

What I did:

1) Made sure all the latest (pending) apple system updates were installed

2) Formatted ext HD then created a fresh Time Machine disk

3) Formatted My MAC

4) Reinstalled OS X from bootcamp

5) Formatted Usb stick

6) Created Win Installer & partitioned Bood drive using bootcamp assistant

7) Installed Win 10 bootcamp

8) installed chrome in windows

9) began installing Malware Bytes in windows while simultaneously downloading bit defender

What I expected to happen:

1) Continue my initial windows setup and configuration

2) go to bed

What happened instead:

1) Without warning the screen went black.

—>note I saw a notification come up during this process saying that my invidia drivers were now game ready or something, however I was using windows for at least another 10 - 15 minuets Before the screen when black.

2) computer still boots up and I hear the wrong key beep(?) when feeling around (see below)

What troubleshooting have I attempted?:

1) reboot

2) PRAM reset

3) SMC Reset

4) connecting the MagSafe charger

5) Holding option during boot up, then blindly trying to login to windows and OS X, to try adjusting the screen brightness

What results have I seen from my Troubleshooting? (Corresponds to previous section)

1) nothing.. it boots black

2)

nothing.. it boots black

3) MagSafe changed colour briefly

4) The first time I attached the MagSafe the screen came back then disappeared. (Estimate less than a minute)

5) the aforementioned beeping noises when touching non F# keys... and still nothing

———————————

I would be grateful for any help that you can provide...

Thanks
