How to fix the BUGCODE PSS MESSAGE SIGNATURE Error?

If you encounter the BUGCODE_PSS_MESSAGE_SIGNATURE error, Windows can’t initialize, which means you won’t be able to access data stored on your computer. Also known as the BSOD (Blue Screen of Death) error or STOP 0x000000c3 error, this problem can cause Windows users to be scared and left wondering what to do next.

Luckily, this guide offers a step-by-step approach on how to fix the Bugcode_PSS_Message_Signature error.

What is the Bugcode_PSS_Message_Signature error?

This is an error that usually appears during Windows startup. The main cause of the Bugcode_PSS_Message_Signature error is corrupt system files. When an application running on your system replaces a system file, your computer is forced to shut down to prevent the loss of data.

Windows verifies the validity of files, and if there is an invalid file signature, you’ll see the STOP 0x000000c3 error on the screen when you turn on your computer.

Another reason for this error is damaged Windows system files, which occurs due to an incomplete installation or un-install process of an application or program. Similarly, failure to properly delete a device or an application as well as a malware attack could damage system files.

Fortunately, you don’t have to be an expert to fix this error. Below, we provide several ways on how to fix the Bugcode_PSS_Message_Signature error.

1. Using Automatic Startup Repair

When Windows fails to load properly, Automatic Startup Repair is the first option you should try to fix the error.

2. Select “Troubleshoot” from the “Choose an option” window.
3. Click “Advanced options.”
4. Select “System Restore,” and follow the instructions.
5. This action removes installed apps that may be affecting your system files.

For Windows 7:

3. Press any key for your computer to boot from either the CD or DVD.
4. Wait for Windows to load files, and then choose your preferred settings.

8. Wait for Startup Repair to check for problems in your system files.

10. Click “Finish” to restart your computer and see if the error is fixed.

System Restore is a Windows feature that allows you to revert your computer to a previous state. It’s an important step when you’re trying to solve a major issue in Windows. You can use System Restore to undo any changes caused by the Bugcode_PSS_Message_Signature error.

To perform a system restore on Windows 10, 8 or 8.1:

6. Click “Next,” and then click “Finish.”
7. Next, you’ll see a screen with the message, “Once started, System Restore cannot be interrupted. Do you want to continue?” Click “Yes.”
8. Your computer will restart after the process is complete.

To perform a system restore on Windows 7:

1. Click “Start,” and then type system restore.
2. Select “System Restore” from the results.
3. Click Next > Choose a different restore point.
4. Click “Next,” and select a restore point.
5. Click Next > Finish.
6. Select “Yes” to confirm.

Wait for the process to complete. If Windows starts normally, then the error has been resolved. If it doesn’t, then try the next solution.

3. Using Auslogics BoostSpeed to scan your Registry

The Bugcode_PSS_Message_Signature error can be caused when the installation of an application is not done correctly. Likewise, if an app is uninstalled incorrectly, you’ll need to clean your Windows registry.

We recommend using Auslogics BoostSpeed to scan your Windows registry to identify and remove invalid entries as well as corrupt keys. The tool performs several maintenance tasks, including checking your whole system to find files that might be causing the error. This ensures that your system is stable and doesn’t have startup or performance issues.

This command will scan your system and try to fix the affected files.

1. Press the Windows Key and type cmd.
2. Right-click the first option and select “Run as administrator.”
3. Type the command sfc /scannow.
4. Hit Enter.

This process will take some time, and it’s important that you don’t interfere with the process. After it’s completed, restart your PC to check if the error has been resolved.

The Blue Screen of Death is mostly caused by a corrupt Windows Registry. To ensure a healthy PC, always use Auslogics BoostSpeed to maintain a clean registry and keep your machine optimized.
