I just wanted to share "great news".
(I still have same hard drive)
My PC had gotten BSoD when I was trying to do something outside of BL. Obviously after trying to close Windows Explorer, it gets same BSoD.
But then something interesting happens after I restart it
After the following boot animation, my Hard drive makes a noises again and my monitor goes blank leading straight to a smaller BSoD with the error msg this time:
VIDEO_DRIVER_INIT_FAILURE
So could it be my video driver, or could it be my hard drive... or both!?
It took 2 boots of the same thing, then Windows 10 took me to Repair again and "diagnosed my PC". I went and booted up, and it was normal
