BSOD

I did some things to my computer that crashed it. I got it mostly fixed, but I now get a BSOD when I boot XP.

The computer is a Dell Dimension E521 with XP Media Center Edition Version 2005 installed. I have run chkdsk on the computer.

The error code I am getting is c000021a with status 0x000014f (0x00000000, 0x00000000). Check the attachment for the complete message.

I replaced C:\Windows\System32\winlogon.exe and csrss.exe with the C:\Windows\ServicePackFiles version.

If anyone can tell me something about what is the problem, that would be great.

Thanks in advance.

 

How to do a Manual SYSTEM RESTORE in XP

A. Connect your non-bootable hard drive to another computer, as a secondary drive or use a usb adapter or enclosure, If you can see your data on the drive, back it up Now, then follow the rest of these instructions.

B. Open Windows Explorer. Click on Tools|Folder Options|View. Check the box beside "Show hidden files and folders". Apply your change.

NOTE D: may not represent the hard drive you connected to your PC, it may be E: or F: or G:, it all depends on how many other drives (including cd/dvd) you have in your host PC, So substitute the appropriate drive letter in the instructions below.

C. Navigate to the D:\System Volume Information folder. You will see a folder named something like _restore{.........} the dots represent an alpha-numeric sequence.

In this folder you will see folders named RP0....RPnn. Find the one with the highest number.

These are your System Restore points. In the highest numbered folder you will see a folder named snapshot. In this folder are registry hive files which you need to recover your system:

_registry_user_.default

_registry_machine_security

_registry_machine_software

_registry_machine_system

_registry_machine_sam

D. Create a subdirectory; i.e, D:\Windows\TMP. Copy these files to the TMP subdirectory. Rename them to:

default

SECURITY

software

system

SAM

Note Be sure to lose the period (.) in the file named _registry_user_.default

E. Delete the files in the D:\windows\system32\config subdirectory with the same short names.

F. Copy the D:\windows\tmp files to the D:\windows\system32\config. subdirectory.

G.Put your drive back in its original system. Your system should start normally. If you get the same error repeat the procedure and choose another folder ( RPnn) (next highest number). You can repeat this procedure choosing lower RPnn numbers until you get it booting again.

If you are denied access to any folders you will have to take "Ownership" of the folders first. http://support.microsoft.com/kb/308421

If this procedure fails to work you need to repair or reinstall Windows.

 

Thanks for the advice. I'm running a backup right now...
Actually, when you have another operating system on your hard drive you don't need another computer! Ha ha! My policy is "If you have space on your hard drive, install another OS." Which goes to show what a computer geek I am.

Updates to follow... stay tuned!

 

I did the manual system restore. I never knew you could do that!
Now it just boots to the loading screen and then freezes (see attachment). Any ideas?

 

from the recovery console run fixboot , disregard any message and just type Y for yes

 

I should have said that it freezes right before the login screen. Fixboot didn't help.
???

 

the fix for this issue is a restore point, can you do the manual restore to a point further back from the one you chose already?, barring this fix, you may have to boot to hiren's or linux boot disk, get your data off the drive and reinstall xp

 

Well, the system restore method was not the solution. However, I replaced csrss.exe, which fixed it!

 

good work
