BAD_SYSTEM_CONFIG_INFO

STOP: 0x00000074

 
  Description  
     
 

The registry is corrupt and is not usable. This can occur if you manually edited the registry incorrectly, if critical keys or values were removed or there are memory problems.

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.

BAD_SYSTEM_CONFIG_INFO

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.

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.

Use Last Known Good Configuration
8
    Add    Flag
solution icon

If you are unable successfully boot into Windows because of the fatal error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:

  1. Reboot the computer.
  2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
  3. When successful, you should see a black screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.

Restore From Backup or Image

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).

Repair Damaged or Missing OS Files

Use the Windows RE (Repair Environment) under Window 7/Vista to repair and replace missing or damaged files. For XP users, you can re-install XP without erasing applications or settings, or use the XP Recovery Console to fix some problems. Pick the OS solution below.

Using Windows RE for Windows 7/Vista/Server 2008

For detailed instructions with screen shots, go to Using System Restore 7/Vista/2008, or use the brief summary here:

You'll need the Windows installation DVD. Note that many OEM manufactures leave out the installation DVD, which has to be purchased separately, or they only include a limited restore DVD that just erases the system and starts over (often a poor choice). All retail copies of Windows include this bootable DVD.

Insert the Windows DVD and reboot the system. Assuming the BIOS defaults to booting from the DVD (usually the default) then select the language. Next click on Repair your computer. A list of Windows installations should appear. Select your installation (typically there will only be one).

A list of recovery options will appear including an automatic repair function, restore from a previous system restore point, restore the computer from a backup (assuming one is available), run the memory diagnostic tool, or go to a command prompt (for advanced users).

Using Windows Recovery for XP

For detailed instructions with screen shots, go to Using System Restore XP.
