STATUS_IMAGE_CHECKSUM_MISMATCH

STOP: 0xC0000221

 
  Description  
     
 

A device driver or a system DLL failed Windows integrity check and has been corrupted or altered.

The path and filename of the damaged file is normally shown as part of the BSoD Stop message.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

 
   
  Sample Screen  
     
 

A problem has been detected and Windows has been shut down to prevent damage to your computer.

STATUS_IMAGE_CHECKSUM_MISMATCH

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Fix Improper File Restore
5
    Add    Flag
solution icon
If you just restored from a backup, the backup may have failed to save key system files that were in use at the time of the backup. As a result, the restoration would restore some system files, but not others. This can cause different versions and/or a failure to repair some damaged system files.

This is a bit of a mess, and not easily solved. If you have a another complete backup, you might try it. You might also try using the Recovery Console to restore system files.

Fix Damaged Pagefile

The page file may be corrupt. To fix this:

  1. Boot into the Recovery Console command prompt from the Windows boot installation CD/DVD.
  2. Delete the Page File, which is in the system root directory by typing: del pagefile.sys
  3. Next you need to run the check disk by typing: chkdsk /r
  4. Exit the recovery console and reboot into Windows.
  5. You'll need to create a new pagefile and/or verify the settings.
    For Windows 7, Vista and Server 2008:
    • Select Start, then right-click on Computer, and select Properties.
    • Select Advanced system settings.
    • In System Properties, select the Advanced Tab, and under Performance, select the Settings button.
    • In Performance Options, select the Advanced Tab. The lower box Virtual Memory shows the paging file size. If it is off or set wrong, you can change the options using the Change button. Typically the "Automatically manage ... " option is best.
    For Windows XP Server 2003:
    • Select Start, then right-click on My Computer, and select Properties.
    • In System Properties, select the Advanced Tab, and under Performance, select the Settings button.
    • In Performance Options, select the Advanced Tab. The lower box Virtual Memory shows the paging file size. If it is off or set wrong, you can change the options using the Change button. Use either System managed size or custom size.

Restore From Backup or Image
5
    Add    Flag

If you know the hardware is good and you have a current backup or image of the drive, you could reformat the hard drive and start over. This is often the last resort when all else fails, as you will often lose your latest settings and important data. If you have a spare drive, it may be worth it to install the drive in place of the first drive and do a fresh install of Windows. This will help confirm if this is a hardware or software issue (unless the original system drive is the source of the problem).

Check Memory

You may have a defective memory. This is even more likely if it only occurs when the system is cold or hot, but not all the time. Use a memory tester to confirm if it is defective or if you have spare memory, try replacement.

Windows 7 and Vista include a Memory Test program when booting from the Windows Installation DVD. Step-by-step instructions with screen shots are available at Using System Restore on 7/Vista/2008 as part of System Recovery.

Several software products that also provide memory and video diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

Additional Memory Solutions:

  • Confirm all the memory is of the same type and speed. Many motherboards only work correctly when the memory is installed with matched sets and matched speeds.
  • If you added or changed your memory just before this problem occurred, try reverting to the prior memory configuration to confirm it's the source of the problem.
  • Check that the memory is fully seated in the sockets. Memory sockets often have side latches that need to be upright to indicate the memory is correctly locked in place.
  • Confirm the memory resides in the correct slots on the motherboard. You'll need to refer to the motherboard manual to confirm this. There is little consistency, even within a single vendor. Some systems require that memory is installed as matched pairs, but not always adjacent to each other!
  • It's also possible the memory problem is on the video card, as they often contain additional memory. The video card should be tested and/or try a different video card to see if the problem goes away.

Fix Defective Hardware

Confirm the hardware is working correctly using a hardware diagnostic program. If you suspect a specific hardware item, such as memory stick or video card, try replacing it with known good hardware.

Don't overlook the possibility that hardware was not installed correctly, especially anything you installed just prior to the problems starting. Make sure all cards and memory are securely seated in their slots. Verify disk drive cables are properly connected and are not loose.

Several software products that offer an extensive range of hardware diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.
