I'm facing issues with booting of my out of warranty on 10/11/17 Alienware 17 R3, Nvidia 980M gpu laptop.

The story:
I left my laptop on overnight and woke up to see the apps were frozen/ barely responsive.

I decided to reboot it but now, after the initial Alienware logo, I only see a lit black screen. The fans rev up full speed, as is the case during normal booting but I don't see anything on the screen (Call this case 1)

The Caps lock and Num lock indicators are working fine during this black screen.

However, sometimes on boot I get a Blue Screen with the Error code: 0xc000000e. With either "Device missing or inaccessible" or "Operating system file missing or has some errors. File: \Windows\system32\winload.exe (call this case 2)

 I ran the ePSA diagnostics and it returns all tests passed, everything is ok. I was advised on the Alienware subreddit by AW_Support to try power drain, but that hasn't helped either.

Essentially the booting process results in case 1 or case 2 (refer above).

What do I do now?
