Stop 0xC0000221 or STATUS_IMAGE_CHECKSUM_MISMATCH

This Stop message indicates driver, system file, or disk corruption problems (such as a damaged paging file). Faulty memory hardware can also cause this Stop message to appear.

Possible Resolutions:

• You can use Driver Rollback or System Restore from safe mode, to restore a previous driver. You can also use Windows XP Professional recovery features such as the Last Known Good Configuration startup option, Backup, or Automated System Recovery to restore a previous working configuration. After restoring from backup media, you might need to reapply service packs or hotfixes, depending on when the backups were made.

• If the Stop message names the specific file, try replacing it manually with a fresh copy from the Windows XP Professional operating system CD using safe mode or Recovery Console. For systems using the FAT16 or FAT32 file system, you have the option of using a Windows 98 or Windows Millennium Edition Emergency Boot Disk to access the hard disk.
If the original file from the operating system CD has a file name that ends with an underscore (_) character, you cannot use the file until it is uncompressed. The Recovery Console's Copy command is ideal for copying compressed files because it detects and expands them. If you do not specify a destination file name, you must rename the expanded file with the correct extension before using it. From safe mode or Recovery Console, you can use the Expand command to uncompress and copy a file to a destination location. In Recovery Console, the expanded file is given the correct name after being copied to the destination location. For more information about the Copy or Expand commands, see Windows XP Help and Support Centre.
