Black Screen of Death

[rawwritsmikey]

First of all, I hope this is the correct section to put this in. For the past 4 days, I have been trying to fix my computer but I am stumped. My computer is running Windows 7 Professical 32 bit. On Sunday night, I turn on my computer. It starts up like normal, until screen where it asks if I want to boot into Startup Repair (Recommended) or Start Windows Normally. I think nothing of it and just start it normally. After I select that, it reboots and goes back to that boot screen. Naturally, I just let it run Startup Repair. I let it run overnight and in the morning I find my computer with a black screen and movable cursor. I didn't think much of it, so I rebooted and the black screen persists. I look up possible solutions for this (I later found out this problem is called the a Black Screen of Death or KSOD) but have failed to discover a solution.

The following are all the solutions I have attempted:
CTRL+ALT+DEL = nothing
CTRL+SHIFT+ESC = nothing
SHIFT = nothing
Above key combinations with all safe modes = nothing
Safe Mode = black screen with cursor
Safe Mode w/ Networking = black screen with cursor
Safe Mode w/ Command Prompt = black screen with cursor
Last Known Good Configuration = black screen with cursor
Low resolution boot = black screen with larger cursor
Startup Repair = Could not fix problem automatically
System Restore = Could not find restore point
System Image Recover = Could not find image
Windows Memory Disgnostics = nothing
SRC Scan = Unable to scan and says I must restart to scan
Unplug external devices = nothing
Mashing random keys = nothing
Letting the black screen sit overnight = nothing
I have also tried other commands in command prompt but have forgotten what they are.

I am completely stumped. This black screen was completely unprovoked. Nothing out of the ordinary has occured. The only thing I have noticed new is a new intel splash screen at startup, but that can't mean anything. I can't afford to do a complete system restore as I have important files on that computer needed for school. If anybody has any other methods, I'd greatly appreciate it. If any other info is needed, I'll willingly provide it.

Just an status update:

@Jacee your link didn't really help me. I don't know how to take apart a computer.

All chkdsk commands are not effective.

Apparently, unbeknownst to me, my BIOS setup has a password that I don't know so I guess booting stuff from a disc is not an option. :/

Deleting Logs and loading hives in Regedit did not work.

And I am have an HP Media Center 8407c PC for those who need the specs.

None of those options worked for me. The disc options might but I cant get into the BIOS setup because it has a password. I have gotten into it before without a password so I don't know why it has a password now. Also, I think it is worth mentioning that the windows logo no longer appears on the start windows splash screen. I hope anybody else has suggestions.

I thought I'd update this thread with more info that may be useful and to see if anyone else could help.
First of all, this problem started after I forced shut down my computer by holding down the power button. This is how I usually shut down my computer though.
After looking at the startup repair diagnostics, I discovered that it was failing because of no OS was installed. This sounds mighty suspicious. Here are the diagnostics and problem signature: (sorry about the last one, its hard to type and edit this n a tablet)

Obviously you need to be able to boot a disk to repair in this situation. The steps in Troubleshooting Windows 7 Failure to Start cover everything that can be done in the sequence they should be run.

You don't have to boot into BIOS setup to boot a disk. Tap the HP ESC key at boot to trigger the disk or flash stick.

To enter BIOS setup if you didn't set up a BIOS password then try just clicking Next if prompted for Password. If that fails reset the CMOS using one of the options which don't require booting into a BIOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS.

Then work through the steps. Have you tried Safe Mode to run Malwarebytes? You may be infected.
