BSOD C0000221 Unknown Hard Error - XP Pro

Hi guys!


I am using a Stealthtouch M5, running on Windows XP Professional. I am now stuck in a boot loop after it shut down abruptly due to power outage, it will just automatically restart before getting into the logon screen. I have tried disabling the automatically restart, but by doing so I will get the BSOD with the following error:


STOP: c0000221 unknown Hard Error
\SystemRoot\System32\ntdll.dll


Furthermore, I have also tried booting up into Hiren's Mini Windows XP to run a chkdsk on the hard drive, and ran a virus scan with Bitdefender, even after deleting the infected file on the hard disk, I am still getting the same error.


After that, I attempted to boot it up from a bootable USB containing Windows XP Professional OS but unfortunately it will just stuck on the "Press any key to boot from USB" after a key is pressed. To confirm that the USB should be bootable, I have successfully boot it up on another computer. So I am not sure why it just doesn't work.

Suspected of corrupted system files, I tried fixing it with another computer running Windows 7, with the command,


sfc /scannow /offwindir=d:\windows /offbootdir=d:\


but unfortunately it says "Windows Resource Protection could not start the repair service", is there any other way I can run this command?


I am really out of ideas to fix it, can someone please give me some advice?


Thank you so much!!

 

Answer

In Advance boot options (Safe Mode) have you tried the other options like the  "Last known good configuration"?

If that would not work see this article if it could help:

http://pcsupport.about.com/od/fixtheproblem/a/ntdlldll.htm

Since you can't start the computer you can start your trouble shooting on item number 8, that is "Test your memory for damage". If you can't perform the Memory test and you have two sticks of RAM, remove one alternately and check or you can use/borrow RAM from a known working computer.

How To Fix “STOP: C0000221” Error On Windows XP

The STOP: C0000221 error is a very common error Windows XP and other versions of Windows. This error normally appears on a blue screen and restarts your PC. Fortunately, it’s quite easy to fix if you know what causes the problem in the first place and how to remedy the issues surrounding it.

What Is The STOP: C0000221 Error?

The STOP: C0000221 error is a typical error for when a critical file fails to load on your PC. The file and specific cause of the error can be varied, but the main way to fix this issue is always the same. Here are some of the typical errors that depict the STOP: C0000221 issue:

STOP: C0000221 unknown hard error
\

STOP: 0xC0000221 unknown hard error
C:\Winnt\System32\Ntdll.dll (or another specific file or driver)

STOP: 0xC0000221 STATUS_IMAGE_CHECKSUM_MISMATCH
Path\File_name

In order to fix this error, you must look at several different steps which will cumulatively fix the problems that cause the error.

Causes Of The STOP: C0000221 Error

This error is caused by a similar array of problems which make Windows unable to read the files that Windows has inside. Typical problems include:

  • A device driver is malfunctioning or is damaged. This causes Windows to be unable to use a piece of hardware that Windows needs, which causes the error.
  • Windows is unable to read the files it needs to run. These files could be .dll files or similar.
  • You have a virus or other infection which hampers Windows’ ability to perform the tasks and commands that you want.

Here’s what you need to do to fix it…

How To Fix The STOP: C0000221 Error

Step 1 – Update The Drivers On Your PC

The main cause of this error is to have drivers that are either outdated or damaged, and in order to ensure this is not a problem, you should try and update all the drivers for your system. The easy way to do this is to click onto the website for the company who manufactured your computer and then go through all the drivers they have on their site, installing them as you go. Alternatively, you could also try and use a program called “Driver Robot” to update your computer’s drivers – this is a tool that scans through your computer and updates your drivers automatically.

Step 2 – Run Antivirus Scans

– Download This Antivirus Program

Download Windows Repair Tool

Antivirus programs are software tools which scan through your PC and remove any of the viruses or malware infections that are on your system. It’s often the case that viruses will infect various important Windows files on your computer and then cause them to be unreadable to your PC, leading Windows to show the error you are seeing. To ensure this is not happening on your computer, you should try using an antivirus program to scan through your system and remove any of the infections that cause all these errors. You can download our recommended antivirus program from the link above, but there are a large variety of programs available.

Step 3 – Repair Windows

– Tutorial for XP

– Tutorial for Vista

– Tutorial For Win7

A great way to repair this error is to perform a repair installation on your Windows PC. A repair installation is basically where Windows will repair all the damaged files and settings that are on your PC whilst keeping all your personal settings and information. This basically wipes the slate clean in terms of corrupted system files, and should stop the error you’re seeing if it’s been caused by a particular file or problem inside Windows itself.

Step 4 – Clean The Registry

– Download This Registry Cleaner

The ‘registry’ is a big database inside Windows which keeps a large list of references for the system files on your system. This central database is where Windows keeps a list of the system file locations for your computer, and is where your system looks each time it wants to use a program or files that it has. Unfortunately, it’s prone to becoming damaged and corrupted and is constantly being unable to read the files and references that it needs to open the files that it wants. This is a major problem that causes a lot of damage to many different parts of your system. Running a registry scan will remove all the damaged references inside the registry, allowing it to run as quickly and smoothly as possible.

  • STOP: c0000221 Unknown Hard Error\Systemroot\System32\ntdll.dll

    I have a Dell Vostro 1500 running Windows XP Home edition.  During the Windows boot the system falls down and shows the error in the title above. I replaced and improved hard drive and modules memory live with Dell components and tried to launch the system to start disk.  Same result screen, blue with the unknown hard Error\Systemroot\System32\ntdll.dll STOP: 0000221.  Then new hardware configuration and system bootable drive equals the same result.  Any advice will be appreciated.

    Thank you, everyone, for all the good advice and help. Interestingly, I used a reinstall drive different (one for the same version of Windows XP SP2), and it worked fine. I think this would indicate that the original disk could have been the cause of the problem, but I tried to install the operating system with this drive just to be safe, and it worked. It should be noted that I did no changes to the machine until I tried the new disk, then retried first that I tried to use to reinstall the operating system. This suggests that, regardless of the problem, he don't has not been caused a constant problem.

    My Dell crashed.   When I try to restart, it will start not (in any mode): can't go in Safe Mode or last mode of work or other.   I managed to get to the blue screen and I saw the following: STOP: c0000221 Unknown Hard Error\SystemRoot\System32\ntdll.dll

    I did some research that says I can try to reinstall / Windows XP Recovery and that this could make it work

    I have all the original disks.

    Can I use the Microsoft XP disk and how can I reinstall without wiping my hard drive (I'm terrified by wiping my hard drive)

    The manual of Dell said to insert the Windows XP installation disk and I have the ability to REPAIR, not REINSTALL

    Will this work?

  • STOP: c0000221 Unknown Hard Error\Systemroot\System32\ntdll.dll mean I lost my hard drive?

    Does this mean I lost my hard drive? Do I need to use the ERD? I don't understand not anywhere with F8 or F10, just the message of the screen and stop.

    You have never actually seen, made an effort to replicate it and never actually solved this problem before, have you?

    Give me instructions on how to apply the resolution alleged in the article:

    To resolve this problem, obtain a new copy of the corrupted file or reinstall Windows XP. If you continue to receive one of the error messages that are described in the "Summary" section after you have reinstalled Windows XP, a hardware problem or network may exist.

    Tip: I don't have XP CD and there is no "Summary" on this page.

    It seems that you come to search Bing and post a link to the first MS KB article that appears.

    Don't you think it might be a bad CD/DVD player, a bad cable CD/DBD or little RAM bad?

    Why not unplug/uncable the CD/DVD drive and then see how things work?

    Of course, we don't know if there's a since the forums MS Answers does not prompt for any information system when a new question is asked, but that's what I would say.

    Hello

    I saw the 0x0000007B BSOD caused by trying to install XP on a disk hard while the BIOS is designating the reader as AHCI instead of IDE. XP has no native AHCI drivers, resulting in a stop 7B. Unless the PC had originally Vista or Win 7, but it might be useful to check that it is not likely.

    If the BIOS is set to AHCI, you could do one of three things (depending on whether your PC has a floppy drive)...

    1 find the Setup F6 disk on AHCI support at installation time (start with the manufacturer's website if you do not already have such a thing). Watch the very hit F6 prompt early in the installation process.

    2. change the setting in BIOS on IDE / ATA

    3. create a new "slipstreaming" installation disc drivers AHCI in the existing installation disc, see http://www.nliteos.com/index.html

    After the back if your BIOS is IDE / ATA

  • When I try to reinstall Windows XP on my Toshiba laptop, it works until I reboot. Then it says nvrd32.sys not found: press any key to continue.

    original title: NVRD32. SYS ERROR

    When I try to reinstall Windows XP SP3 on my Toshiba laptop, it works until the first reboot. When I boot on CD it comes up saying nvrd32.sys is not found: press any key to continue. When I press a key it is said: the Installer failed. Press a key to restart your computer.

    So, I don't know what to do. I tried searching on google and found a set, but talk of computer that I couldn't begin to understand. Basically, what I consider somewhere or can I fix it myself? I just paid for a new disk of Windows XP SP3, so I'm not looking forward to having to pay someone to use it.

    Hello

    ·         Windows XP came preinstalled on your laptop?

    ·         If so, you have a recovery partition?

    ·         Where did you buy the disc of Windows XP SP3 for?

    nvrd32.sys file is a chipset driver and must be installed via floppy F6 during initial installation.

    Method 1: To do this, follow these steps.

    a. you can download the chipset drivers from Toshiba Web site and copy it to a floppy drive.

    b. press F6 at the start of the installation of Windows XP.

    c. follow the on-screen instructions to install the drivers for the chipset.

    Method 2: You can contact Toshiba to restore to factory on the laptop.

      Resolved [RESOLVED] BSoD : C000021a - Unknown Hard Error

      Can anyone tell me more info about this? Initially I suspected it was a hardware issue. Therefore, I reset CMOS, problem remains, Checked my Maxtor Harddisk (with PowerMax), no problem found, Checked my DDR400 SDRAM (with Memtest), no error found. Any idea?
      Thanks in advance.

      Have you got pcAnywhere on that PC?

      TEk


    3. February 28th, 2008, 09:08 AM#3

      Yes, it can be a software problem too

      If it is not TEk`s suggestion, can you boot to the Safe Mode Options screen? Try a System Restore from here

      Boot into Safe Mode by pressing F8 at bootup and choose
      'Safe mode with command prompt'

      At the command prompt type
      C:\Windows\system32\restore\rstrui.exe

      Hopefully System Restore will open so choose a Restore Point a few days ago.

      If that does not work I think you will have to do a Repair of XP

      That Stop Error is usually Registry corruption. This KB article can be useful:

      Thanks for reply. I didn't use pcAnywhere. System restore is not needed as I saved an image before the problem occurs, therefore I can roll back to the point before the problem starts. However, whenever I install those softwares back, the error comes again. I think it might be a software conflict but just can't find the culprit. I suspect more on windows security updates because every software that I installed on this pc, I installed on another pc as well and it was always run smoothly. The only different is this one is an old pc (Cel. 1.7GHz CPU, 512MB DDR400 SDRAM which shared 32MB to the onboard graphic card.) Since the softwares I use don't require a powerful pc, therefore I think this pc should be enough to run just fine.
      If you would like to know what I've installed, please read below:

      Driver for Devices, DirectX 9.0c, windows installer 3.1, dotnetfx (1.1, 2, 3), some security updates, WMP 11, IE 7, Java Runtime Environment 6 update 2,
      Flash Player, Shockwave, Regcleaner, CCleaner, Auslogics RegDefrag, Tweakui XP, Vopt XP 7, UberIcon, CursorXP,

      There are still many softwares I want to install, but at this point problem already occurs.
      Any idea?


    6. February 28th, 2008, 12:23 PM#6

      Another information I think should be useful. I use a boot CD to diagnosis problem. I discover that whenever I want to enter a Disk Partitioning tool, I met with a Critical Error (before the problem occurs everything runs fine). Then I have to choose Abort, Fail, Ignore, Retry. However if I was going to the Diagnosis section like Maxtor PowerMax & Memtest, everything runs well. seems to me like harddisk problem but I did ran a test last night with PowerMax & no problem found. Any idea would be much appreciated. Thanks!

      Corrupt programs on the cd will do that too.

      Probably got a bad download to start with.


    8. February 28th, 2008, 02:36 PM#8

      Definitely not cd problem. As I've been success to load the program without error before.


    9. February 28th, 2008, 02:40 PM#9

      Have you used a lens cleaner cd and cleaned the cd too.

      Had either one or both of them being dirty bite me many a time over the years.

      Also one of the reasons why I learned to burn at slower speeds as that does a better job of burning and helps stop future problems.

      Problems that have bite me.

      Finally... .
      The damn mainboard is the source of error. I use PC Doctor to do a system stress scan. It hang when testing the RAM. Other section like harddisk, CPU, CD-ROM got no problem. Wondering how come Memtest can't detect any error? Then I place the RAM to another mainboard & ran the same test. This time no error occurs. Means problem start with the RAM slot or somewhere on the mainboard.
      If it was the faulty of RAM slot, any advices? I tried both slot & both have a same problem. Thanks for your help.


    11. February 29th, 2008, 03:03 AM#11

      If memtest does not find any errors, that is when I run the Windows Memory Diagnostic http://oca.microsoft.com/en/windiag.asp

      Have you cleaned the ram contacts with a pencil erasure? I have had that help out. Corrosion which we may not see does build up.


    12. February 29th, 2008, 07:40 AM#12

      Hello:
      Thanks for reply. actually I tried to clean the contacts with an eraser yesterday but it didn't work for me. I'm thinking of clean it with some kind of alcohol but found lots of people say it is not recommended to do so. Maybe can I claim a warranty? It's a Kingston PC3200 SDRAM so I think it should have a lifetime warranty.


    13. February 29th, 2008, 11:56 AM#13

      I would try.

      Got a stick laying around or you can borrow that would fit? Try that one.


    14. February 29th, 2008, 12:24 PM#14

      While very useful, those memory testing utilities cannot test for every possible error. The only sure fire way of testing the RAM stick is with a hardware memory tester - if you have a local PC repair shop they should be able to test it for you.

      Nick.

      Hi:
      Finally got a replacement for the RAM. However, When I'm installing windows, the PC power off suddenly. Then it will be unable to power up. Then I have to adjust/reseat the RAM then it can power up again.
      Since the RAM is a new one, I think it is most probably the faulty mainboard. I tried both slots on my mainboard, same problem occurs. Any method I can try to make sure is it the problem of the mainboard?

    In Advance boot options (Safe Mode) have you tried the other options like the  "Last known good configuration"?

    If that would not work see this article if it could help:

    How To Fix Ntdll.dll Errors
    http://pcsupport.about.com/od/fixtheproblem/a/ntdlldll.htm

    Since you can't start the computer you can start your trouble shooting on item number 8, that is "Test your memory for damage". If you can't perform the Memory test and you have two sticks of RAM, remove one alternately and check or you can use/borrow RAM from a known working computer.

To confirm that the USB should be bootable, I have stop c00002la unknown hard error boot it up on another computer. So I am not sure why it just doesn't work.

    Suspected of corrupted system files, I tried fixing it with another computer running Windows 7, with the command,


    sfc /scannow /offwindir=d:\windows /offbootdir=d:\


    but unfortunately it says "Windows Resource Protection could not start the repair service", is there any other way I can run this command?


    I am really out of ideas to fix it, can someone please give me some advice?
