Laptop wont do anything

I have left my laptop aside for some time now, as I have a horrible time with it.

It all started after I had simply closed my laptop without turning it off. When I wanted to use my laptop again, it wouldnt get out of the sleep mode, so I restarted it instead, getting the recovery option which I did.

Then since then whenever I want to boot my computer, I get a blue screen. I have been able to do/find out the following:

- All 3 safe mode options give me a blue screen.
- Windows Repair won't load
- Windows Setup won't load (I tried to do a clean installation)
- Last known good configuration gives blue screen
- Blue screen gives error unmountable_boot_volume
- Disconnected DVD-rom in BIOS
- Ran memory test
- Tried running System Recovery with the Windows disk pressing 'R' in the setup screen, which starts but won't load fully to the point that me clicking on the next button will work.

I am still left without any results, so now I am here asking for your solutions.

Well, I managed to boot into the Windows Install program, until the screen where it says Install Now.. I pressed the "R" button, which let me to the Recovery Settings screen.. this might take a while to load, but eventually it did.. I booted the command prompt and followed a video on youtube I had found on how to reformat my disk using the command prompt..

I managed to completly format the disks I had, and was then able to boot the Windows Setup :)
