Below is a list of troubleshooting steps to resolve your Code 43 problems. These troubleshooting steps get progressively more difficult and time consuming, so we strongly recommend attempting them in ascending order to avoid unnecessary time and effort.


Please Note: Click the [ ] image to expand the troubleshooting instructions for each step below. You can also click the [ ] image to hide the instructions as you proceed through each step.

Step 1: Repair Registry Entries Associated with Error 43


Manually editing the Windows registry to remove invalid Code 43 keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely!

Because of this risk, we highly recommend using a trusted registry cleaner such as WinThruster [download] (Developed by Microsoft Gold Certified Partner) to scan and repair any Error 43-related registry problems. Using a registry cleaner [download] automates the process of finding invalid registry entries, missing file references (like the one causing your Code 43 error), and broken links within the registry. A backup is automatically created before each scan, with the ability to undo any changes in a single click, protecting you against the possibility of PC damage. The best part is that repairing registry errors [download] can also dramatically improve system speed and performance.


Caution: Unless you an advanced PC user, we DO NOT recommend editing the Windows registry manually. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. We do not guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to Code 43 (eg. Windows Operating System):

  1. Click the Start button.
  2. Type 'command' in the search box.. DO NOT hit ENTER yet!
  3. While holding CTRL-Shift on your keyboard, hit ENTER.
  4. You will be prompted with a permission dialog box.
  5. Click Yes.
  6. A black box will open with a blinking cursor.
  7. Type 'regedit' and hit ENTER.
  8. In the Registry Editor, select the Error 43-related key (eg. Windows Operating System) you want to back up.
  9. From the File menu, choose Export.
  10. In the Save In list, select the folder where you want to save the Windows Operating System backup key.
  11. In the File Name box, type a name for your backup file, such as 'Windows Operating System Backup'.
  12. In the Export Range box, be sure that 'Selected branch' is selected.
  13. Click Save.
  14. The file is then saved with a .reg file extension.
  15. You now have a backup of your Code 43-related registry entry.

The next steps in manually editing your registry will not be discussed in this article due to the high risk of damaging your system. If you would like to learn more about manual registry editing, please see the links below.

Step 2: Conduct a Full Malware Scan of Your PC


There is a chance that your Code 43 error could be related to a malware infection on your PC. These malicious intruders can damage, corrupt, or even delete Device Manager Errors-related files. Furthermore, there's a possibility that the 43 error you are experiencing is related to a component of the malicious program itself.


Tip: If you do not already have a malware protection program installed, we highly recommend using Emsisoft Anti-Malware (download here). They offer a malware removal guarantee that is not offered by other security software.


Step 3: Clean Out Your System Junk (Temporary Files and Folders) With Disk Cleanup (cleanmgr)


Over time, your computer accumulates junk files from normal web surfing and computer use. If this junk isn't occasionally cleaned out, it can cause Windows Operating System to respond slowly or provides an Code 43 error, possibly due to file conflicts or an overloaded hard drive. Cleaning up these temporary files with Disk Cleanup might not only solve your 43 error, but can also dramatically speed up the performance of your PC.


Tip: Although Disk Cleanup is a wonderful built-in tool, it will not completely clean up all of the temporary files on your computer. Other programs that you frequently use such Microsoft Office, Firefox, Chrome, Live Messenger, and hundreds of other programs are not cleaned up with Disk Cleanup (including some Microsoft Corporation programs).


Because of the shortcomings of the Windows Disk Cleanup (cleanmgr) tool, we highly recommend using a specialized hard drive cleanup / privacy protection software such as WinSweeper [download] (Developed by Microsoft Gold Partner) to clean up your entire computer. Running WinSweeper [download] once per day (using automatic scanning) will ensure that your computer is always clean, running fast, and free of Code 43 errors related to temporary files.

How to run Disk Cleanup (cleanmgr) (Windows XP, Vista, 7, 8, and 10):

  1. Click the Start button.
  2. Type 'command' in the search box.. DO NOT hit ENTER yet!
  3. While holding CTRL-Shift on your keyboard, hit ENTER.
  4. You will be prompted with a permission dialog box.
  5. Click Yes.
  6. A black box will open with a blinking cursor.
  7. Type 'cleanmgr' and hit ENTER.
  8. Disk Cleanup will begin calculating how much occupied disk space you can reclaim.
  9. The Disk Cleanup dialog box will appear with series of checkboxes you can select. In most cases, the 'Temporary Files' category will occupy the most disk space.
  10. Check the boxes of the categories you want to clean and click OK.

Step 4: Update Your PC Device Drivers


Code 43 errors can be related to corrupt or outdated device drivers. Drivers can work one day, and suddenly stop working the next day, for a variety of reasons. The good news is that you can often update the device driver to fix the Error 43 problem.

Finding the exact driver for your Error 43-related hardware device can be extremely difficult, even directly on the Microsoft Corporation or related manufacturer's website. Even if you are experienced at finding, downloading, and manually updating drivers, the process can still be very time consuming and extremely irritating. Installing the wrong driver, or simply an incompatible version of the right driver, can make your problems even worse.

Because of the time and complexity involved in updating drivers, we highly recommend using a driver update tool such as DriverDoc (Developed by Microsoft Gold Partner) to automate the process.

DriverDoc updates all of your PC device drivers, not just those associated with your Code 43 error. DriverDoc's proprietary One-Click Update™ technology not only ensures that you have correct driver versions for your hardware, but it also creates a backup of your current drivers before making any changes. Maintaining a driver backup provides you with the security of knowing that you can rollback any driver to a previous version if necessary. With updated device drivers, you can finally unlock new hardware features and improve the speed and performance of your PC.


Please Note: Your Code 43 may not be related to hardware driver problems, but it's always a good idea to ensure all of your PC device drivers are up-to-date to maximize PC performance.


Step 5: Utilize Windows System Restore to 'Undo' Recent System Changes


Windows System Restore allows you to 'go back in time' with your PC to help fix your Error 43 problems. System Restore can return your PC's system files and programs back to a time when everything was working fine. This can potentially help you avoid hours of troubleshooting headaches associated with Code 43 errors.


Please Note: Using System Restore will not affect your documents, pictures, or other data.

To use System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Click the Start button.
  2. In the search box, type 'System Restore' and hit ENTER.
  3. In the results, click System Restore.
  4. Enter any administrator passwords (if prompted).
  5. Follow the steps in the Wizard to choose a restore point.
  6. Restore your computer.

Step 6: Uninstall and Reinstall the Windows Operating System Program Associated with Code 43


If your Code 43 error is related to a specific program, reinstalling Windows Operating System-related software could be the answer.

Instructions for Windows 7 and Windows Vista:

  1. Open Programs and Features by clicking the Start button.
  2. Click Control Panel on the right side menu.
  3. Click Programs.
  4. Click Programs and Features.
  5. Locate Code 43-associated program (eg. Windows Operating System) under the Name column.
  6. Click on the Windows Operating System-associated entry.
  7. Click the Uninstall button on the top menu ribbon.

  5. Click on the Windows Operating System-associated entry.
  6. Click the Uninstall/Change on the top menu ribbon.
  7. Follow the on-screen directions to complete the uninstallation of your Error 43-associated program.

After you have successfully uninstalled your Code 43-associated program (eg. Windows Operating System), reinstall the program according to the Microsoft Corporation instructions.


Tip: If you are positive that your 43 error is related to a specific Microsoft Corporation program, uninstalling and reinstalling your Code 43-related program will likely be the solution to your problem.


Step 7: Run Windows System File Checker ('sfc /scannow')


System File Checker is a handy tool included with Windows that allows you scan for and restore corruptions in Windows system files (including those related to Code 43).

To run System File Checker (Windows XP, Vista, 7, 8, and 10):

  1. Click the Start button.
  2. Type 'command' in the search box.. DO NOT hit ENTER yet!
  3. While holding CTRL-Shift on your keyboard, hit ENTER.
  4. You will be prompted with a permission dialog box.
  5. Click Yes.
  6. A black box will open with a blinking cursor.
  7. Type 'sfc /scannow' and hit ENTER.
  8. System File Checker will begin scanning for Error 43 and other system file problems (be patient - the system scan may take a while).
  9. Follow the on-screen commands.

Step 8: Install All Available Windows Updates


Microsoft is constantly updating and improving Windows system files that could be associated with Code 43. Sometimes resolving your Device Manager Errors problems may be as simple as updating Windows with the latest Service Pack or other patch that Microsoft releases on an ongoing basis.

To check for Windows Updates (Windows XP, Vista, 7, 8, and 10):

  1. Click the Start button.
  2. Type 'update' into the search box and hit ENTER.
  3. The Windows Update dialog box will appear.
  4. If updates are available, click the Install Updates button.

Step 9: Check for Hard Drive Corruption ('chkdsk /f')


While most storage-related, 43 blue screen errors are caused by problems with your hard disk drivers or storage controllers, in some cases these BSODs can be attributed to hard drive corruption.

Over time, your PC can develop errors on the hard disk drive due to repeated, unintended misuse. Improper shut downs, “hard closing” programs, corrupt or incomplete installation of software (eg. Windows Operating System), Microsoft Corporation hardware failure, and power outages can corrupt your file system and stored data. As a result, you may experience blue screen errors associated with Code 43.

Microsoft has included a convenient utility called “chkdsk” (“Check Disk”) to scan and repair hard disk corruption. If the previous troubleshooting steps did not resolve your 43 STOP error, running “chkdsk” may uncover and repair the cause of your BSOD.

How to run “chkdsk” (Windows XP, Vista, 7, 8, and 10):

  1. Click the Start button.
  2. Type 'command' in the search box.. DO NOT hit ENTER yet!
  3. While holding CTRL-Shift on your keyboard, hit ENTER.
  4. You will be prompted with a permission dialog box.
  5. Click Yes.
  6. A black box will open with a blinking cursor.
  7. Type 'chkdsk /f' and hit ENTER.
  8. 'chkdsk' will begin scanning for hard disk corruption that could be causing 43 STOP errors.
  9. Follow the on-screen commands.

Complete list of “chkdsk” commands (Advanced PC users only):

  1. /F – Scans and fixes errors on the disk.
  2. /V – Displays every file name in each directory as the disk is scanned.
    • FAT/FAT32 Drive: This will display the full path and name of every file on the disk.
    • NTFS Drive: Displays cleanup messages.
  3. /R – This command locates bad sectors and recovers readable information (assumes /F).
  4. /L:size (NTFS only) – This command changes the log file size to the specified number of kilobytes. It will display the current size if size is not specified.
  5. /X – If necessary, it forces the volume to dismount first. All opened handles to the volume would then be invalid (assumes /F).
  6. /I (NTFS only) - Performs a less rigorous check of index entries.
  7. /C (NTFS only) - Skips checking of cycles inside the folder structure.
  8. /B (NTFS only) - Re-evaluates bad hard disk clusters on the volume (assumes /F).

Step 10: Test Your Memory (RAM) for Corruption


Sometimes hardware-related Code 43 blue screen errors can be due to memory (RAM) corruption. If you are experiencing random computer reboots, receiving “beep” codes on startup, or other computer crashes (in addition to 43 BSOD errors), it is likely that your memory could be corrupt. In fact, nearly 10% of application crashes in Windows are due to memory corruption.

If you have just added new memory to the computer, we recommend temporarily removing it to make sure it is not the cause of your Code 43 error. If this action resolves your BSOD, this will be the source of your problem, and therefore your new memory is either incompatible or bad. If that is the case, you will then need to replace your new memory modules.

If you haven’t added any new memory, the next step is to perform a diagnostic test on your computer’s existing memory. A memory test will scan for hard memory failures and intermittent errors, either of which could be causing your 43 blue screen of death.

Although later versions of Windows include the Windows Memory Diagnostic Tool, I highly recommend using Memtest86 instead. Memtest86 is a BIOS-based memory testing software, unlike other testing programs that must run within Windows. The benefit is that it allows you to test ALL of your memory for Code 43 errors, while other programs cannot test the section of memory occupied by the software itself, the operating system, and any other running programs.

How to run Memtest86 to scan for memory corruption causing 43 STOP errors:

  1. Grab an unused USB flash drive and connect it to your PC.
  2. Download the Windows MemTest86 USB image.
  3. Right click on the image file, and select the 'Extract to Here' option. Extract the file folder anywhere you can get to easily (eg. your Desktop).
  4. Inside the extracted folder, run the included imageUSB tool, and choose your plugged in USB drive to turn into a bootable drive. CAUTION: this action will erase all data on the USB drive.
  5. Memtest86 will now be installed on your USB and you are ready to test for the possible source of Code 43 errors.
  6. Restart your PC with the USB drive installed.
  7. Memtest86 will begin testing for memory corruption.
  8. Follow the on-screen commands.

If all of the above steps were unsuccessful, and Memtest86 finds memory corruption, it highly likely that your Code 43 blue screen error is due to bad memory. If this is the case, you will need to replace the bad memory to resolve your 43 BSODs.

For additional help, Corsair has a great video tutorial on how to run Memtest86:

Step 11: Perform a Clean Installation of Windows


Caution: We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve Error 43 problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately (download a highly-recommended backup solution) to protect yourself from permanent data loss.

This step is your final option in trying to resolve your Code 43 issue. Reinstalling Windows will erase everything from your hard drive, allowing you to start again with a fresh system. Furthermore, a clean install of Windows will also quickly clean out any and all 'junk' that has accumulated over the normal usage of your computer.


Please Note: If 43 errors still persist after a clean install of Windows, your Device Manager Errors problem MUST be hardware related. If that is the case, then it is likely you will need to replace the associated hardware causing the 43 error.


Recommendation:Scan your PC for computer errors.
