Edit: The issue was solved by using a bootable Windows 10 pen drive. Using this drive, I performed a system restore... and bam!
So, my Windows 10 is really pitching a fit! This all started when I had to force shut down my Windows 10 machine using the power button, because of a total system hang. Then, I turned the machine back on. But NVDA did not come back to life. I tried turning on Narrator, and it wouldn't talk.
So I asked my dad to come and look at my screen. According to him, although the lock screen wall paper was there, even when I pressed keys on the keyboard, the log in box wouldn't appear.
I've tried ctrl alt del, I’ve tried rebooting, nothing works. Any help would be greatly appreciated.
