FATAL_UNHANDLED_HARD_ERROR

STOP: 0x0000004C

 
  Description  
     
 

There may a be a bug in a device driver, system DLL, or the registry is corrupted.

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.

FATAL_UNHANDLED_HARD_ERROR

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.

Use Last Known Good Configuration

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).

Check if you are using the latest hardware drivers, especially the chipset and video drivers. Older drivers are a common contributor to BSoD issues.

You can use a product like Driver Genius or Radar Sync to verify you have the latest drivers and help keep all your drivers up-to-date. If you're comfortable with driver installations, you can individually find and install current drivers.

A some of the most popular driver download sites:

Install the latest Windows software updates. Don't forget to check for non-critical updates too!

To manually get updates, open Internet Explorer (you can't use a non-Microsoft browser for updates).

For IE 8 and later: Click on Safety, then Windows Update. Follow the instructions.


 

For IE 7 and older: Click on Tools, then Windows Update. Follow the instructions.
