STOP: c0000221 Unknown Hard ErrorSystemRootSystem32ntdll.dll

\015 In the box above is the error that comes up everytime that the systm is rebooted. What advice can you give me to correct this problem\015

Answers :

Hardware could be the issue but these errors can vary. Most come from a damaged file itself, corrupt hardware drivers, or issues between Windows and other programs. Ntdll.dll errors can sometimes mean that hardware in your computer is malfunctioning but this is rare.

If it's a single temporary issue a simple reboot should do the trick.

If the error ONLY displays when you use a certain program, uninstall the program, reboot and install the MOST CURRENT version.

If the software has any UPDATES or SERVICE PACKS available, install them. The developers of the software may have found a bug in the program that causes this kind of error and released a patch for it. For most programs, you can click Help or About to check for updates on the toolbar while the program is open and running. Some require you go to the website and check for new versions or updates. Programs should be updated as often as updates are available to avoid problems and maintain security.

3rd party software has a habit of causing these kinds of errors.

You can also try:

Check the Windows Service Pack you're running. For Windows, if you're not running the latest servive pack (which is Service Pack 3) then you should update to the latest one available.

Update hardware drivers.

Disable Internet Explorer Add-Ons - if this error occurs when you start, run, or close IE, and add-on may be causing the problem. Disable on then restart IE, if you still have the problem, disable another and restart IE until you find the add-on causing the issue. You can also install a different Web browser like Firefox (you should always have a back up just in case something goes wrong with IE).

Rename the NLSPATH system variable. If this doesn't apply to your system then skip this step. Reset back to original name if renaming doesn't fix the problem.

Run a test on your memory for damage.

Make sure that the cable connecting the hard drive to the motherboard is securely connected.

Perform a repair installation of XP or completely re-install Windows XP. Of course, if you don't have your computer backed up you will loose all data and have to re-install all programs. If you do this, copy all of your data to an external hard drive, flash drive, CDs, etc.

Repairing or re-installing Windows XP will definitely fix the issue but you will find yourself rebuilding/replacing everything.

Hope this helps. It would have been easier to narrow down the issue and troubleshooting steps had you provided more information about the issue and your system's configuration. Please leave comments if you need further clarification on this solution.
