Windows 7: Blue Screen Fatal Error

Blue Screen Fatal Error

Windows 7.
My electric went off during configurations & I have ended up, after trying to follow the instructions to fix it, with a blue screen with Stop: c000021a fatal error, computer shut down, the verification of a knownDLL failed system process terminated unexpectedly with a status of 0x000012f (0x003aa170 0x00000000 ) the system has been shut down, wrote on it.
I have tried a system restore, putting it back to a date of a previous configuration, but it tells me I do not have enough space on my c drive to carry out the restore.
I, like many more users no doubt, donít want to lose my family photos & videos, as well as work, can this be fixed & can my work be saved?
I canít understand how this can happen. Does this mean that every person who has a computer configuring when the electric goes out, suffers with this?
Thank you.
John

Hi,

Please reconfigure windows to collect the correct info
You want small memory dumps - "MiniDumps"

And here are the instructions for posting:

http://www.sevenforums.com/crashes-d...tructions.html

If you are unable to 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:

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

Please post back any observations / results.

Cheers
