I LOST MY BATTLE AGAINST 'BLACK SCREEN OF DEATH'

Yesterday, my colleague asked me to look at her problematic laptop. What happened was the occurrence of a black screen with only a movable cursor after booting Windows 7 Ultimate. When I googled the problem, the term 'Black Screen of Death' appeared. It seemed that the problem has been troubling users for some time now. Many solutions offered, but none of it could be used to solve her problem.

I used my laptop to surf for solutions. I surf websites, and even youtubes. One of the websites I found detailed the fix, but it was useless for this laptop. This is because I had to pop open the task manager, whereas I could not do so because, after hitting the ctrl+alt+del keys simultaneously, the options on the screen just read = 1.Lock this computer, 2.Switch user, 3.Log off, and 4.Change a password. Then I restarted the laptop and pushed f8 while the Windows loading so that the Advanced Boot Options screen appears. I tried each boot options including last known good configuration, safe mode, safe mode with networking, etc and still left dumbfounded. Then I tried the option Repair your computer, eventually a screen appeared. I tried Startup Repair with no luck; it scanned and finished without repairing anything. Then I tried System Restore also with no luck because, sadly, there was no restore point. When I came down to the dreaded Command Prompt (I said 'dreaded' because I never learn how to use the command; I grew up with Windows), I managed to open the task manager. This was only after I learn some commands from the Wikipedia. I typed explorer.exe in the new task box, but a dialogue box appeared saying 'Windows cannot find explorer.exe'. I tried a suggestion from this youtube also, but to no avail.

It seemed that I had failed to find the solution, and had to return her laptop as is.
