Windows 7: BSOD on Startup - Startup Reapir not working

BSOD on Startup - Startup Reapir not working

On Startup, after POST, I get this BSOD:

STOP: c000021a {Fatal System Error}
The verification of a knownDLL failed. system process terminated unexpectedly with a status of 0xc000012f (0x00360bf0 0x00000000).
The system has shut down.

Upon Reboot, I am advised to go to the startup repair. I select my language, but then it asks me to select an operating system, and Windows 7 is not there. If I run DISKPART it does not detect my hard drives, yet they show up fine in the BIOS and in the Intel RST RAID configuration screen. (2x 240 GB SSD RAID 0) I also have a 2TB HHD that windows cant seem to detect but is showing up everywhere else.

The HHD's purpose was to be the back-up for the Raid array....too bad i never actually backed anything up! Boy do I regret that now.

This build has been running fine for a few months until now. It was last working about a week ago and it downloaded an update for windows. I posponed the restart for 30 minutes or so to finish up a game I was playing and then shut it down for the night. When I turned it on the next morning, this happened.

I have Updated the BIOS to the most current version, as well as the SSD firmware. No change whatsoever.

I am pretty desperate here trying to avoid formatting BY ALL MEANS POSSIBLE. So, any advice is welcome!

Hi,

Code:
 
Stop message 0xC000021A Descriptive text: FATAL_SYSTEM_ERROR
Usual cause: The Windows Logon Process system process terminated unexpectedly.
If you are unable successfully boot into Windows because of the BSOD error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:
1. Reboot the computer.
2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
3. When successful, you should see a black screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.

Advanced Boot Options

If you have the Windows 7 installation cd, insert that in computer and boot up with it:
1. Go into the Windows Recovery Environment by selecting the option to repair your Windows at startup.
2. After it has completed the startup repair, click link that says "View Advanced Options for system recovery and support".
3. A list of options appears. click the command prompt and then type chkdsk f//r. Let that run (it may take a while).

Also run SFC to check the integrity of all Windows 7 system files the same way:
1. Go into the Windows Recovery Environment by selecting the option to repair your Windows at startup.
2. After it has completed the startup repair, click link that says "View Advanced Options for system recovery and support".
3. A list of options appears. click the command prompt and then type SFC /scannow at the prompt.

If you do not have the Windows installation cd try booting into Safe-Mode and selecting "Safe-Mode with command prompt:

http://www.sevenforums.com/tutorials/69585-safe-mode.html

If the previous methods do not work, try a StartUp Repair:

Post back any results/observations.

Last known good config:
BSOD

When it auto goes to the system recovery options, or if I use the install disc to get there:
Can't select an operating system to repair because none are listed. If I continue without selecting one, here are the results
for each option:
Startup repair cannot repair the computer automatically
System restore required an operating system to be selected
System image recovery cannot find the file specified
Memory diagnostic has an error preventing it from running at startup
Command prompt seems to work normally

Boot to safe mode:
Loading drivers into BSOD

Command prompt entries:

Chkdsk c: /f
Cannot open volume for direct access

Sfc /scannow /offbootdir=c:\ /offwindir=c:\windows
Windows resource protection could not start the repair service.

Sfc /scannow
There is a system repair pending which requires reboot to complete. Restart windows and run Sfc again.

DISKPART> list volume
There are no volumes.

Hi,
Try Diskpart again, this time use the command list disk.
What disks are listed? One should be the disk containing your C: drive?
My C:\ drive is Disk 1 on the example, yours may be different.
If disks are listed then follow the highlighted commands to get to your partitions
and look for system as shown, is this present? Post a screenshot.

Make one thing sure .... is the SSD is recognized by the BIOS?

Also, what are the changes you have done recently? Do you use UEFI or Legacy mode?

both SSD's and the RAID array are recognized by the BIOS. im using UEFI. I havent made any changes lately other than the windows update that downloaded the night before the BSOD. after the BSOD, i updated the BIOS via flash drive and updated the SSD firmware via bootable disk. neither of the updates changed my results.

It is kinda odd that the BIOS Is recognizing the SSD, but diskpart is not.

Do you have windows 7 installer Disc? If you try a Startup Repair using the installer disc (not the automated startup repair that you have already tried), does it recognize the windows installation in the disc?

Fairly odd. It means that the installation got corrupted.

Follow Copy & Paste - in Windows Recovery Console to secure all your user data. Back them up externally.

Then start afresh.
