Windows 10 is undeniably one of the most powerful operating systems in the world. Despite this, it is still prone to issues and errors. By now, Windows users do not panic when they see error messages on their computer. After all, they have become common occurrences in the operating system.

One of the issues you might encounter on Windows 10 is the error code 0xc0000005. This can be caused by various problems, including malware infection, low or damaged RAM, corrupted registry files, or incorrect hardware configuration, among others. As we’ve mentioned, errors like this are not uncommon on Windows. So, there are plenty of solutions available online. In this article, we will teach you how to resolve the error code 0xc0000005.

Why do I see the error code 0xc0000005 notification?

Before we try to fix the problem, let us discuss the scenarios associated with it. This way, you will gain a better understanding of the reasons why it appears.

During Windows Installation

While you’re installing the Windows OS, the error code 0xc0000005 can show up and disrupt the process. This is most likely caused by temporary hardware issues or a corrupt hard drive because of bad sectors.

Error Message: “Windows installation encountered an unexpected error…”

While Launching an Application

The error code can also show up while you’re trying to open a program like VLC, Google Chrome, VLC, or any other application on your Windows computer. Since this is caused by some unsigned, invalid, or incomplete DLL files, re-installing the program will not fix the issue. If that’s the case, try one of our methods below.

Error message: “The application was unable to start correctly (0xc0000005).”

While Windows is Accessing a Location or Data

You may be doing your regular computing tasks, and this error code will appear. This problem can affect any Windows application. The reasons behind it can include corrupted drivers, faulty RAM, registry issues, incorrect security update, and virus infection, among others.

Error message: “Exception: Access violation error (0xc0000005) at…”

This problem can also occur while you’re installing the latest updates for your system. Do not worry because you can still resolve this issue using our methods below. However, address it immediately because it can cause indirect or direct data loss. Check out some of the best ways to learn how to resolve the error code 0xc0000005.

Solution 1: Checking your RAM

One of the best ways to fix the error code 0xc0000005 is to replace your RAM. Before you do that, you must confirm that the RAM is the culprit behind the issue. So, switch off your computer, try using another RAM. Once you’ve done that, turn on your computer, then check if the error persists. This is the ideal solution when the problem is caused by physical damage on the RAM connectors or hardware.

Solution 2: Repairing your Registry

When there are corrupt files or keys in your registry, they can cause serious system issues, including the error code 0xc0000005. So, if you previously created a registry backup, we recommend restoring it to fix the problem. However, before you proceed, do note that modifying your registry can be tricky and risky. The simplest invalid or incorrect alteration can cause major problems on your PC. So, follow the instructions below only if you’re confident that you will be able to do them correctly.

Solution 4: Disabling DEP

Windows has a built-in feature that protects the system from damages caused by viruses and other security threats. The Data Execution Prevention or DEP feature is useful in many cases. However, there are programs that are incompatible with it, which is why the error code 0000005 shows up. You can disable this by following these steps:

  6. Click the ‘Turn on DEP for all programs and services except those I select’ option.
  7. Click Add, then look for the executable files that are causing the problem. Add them to the list.
  8. Click OK.
  9. Restart your computer, then check if the issue persists.

Solution 5: Running CHKDSK Utility

It is possible that bad sectors or corruption on the drive are causing the error code 0xc0000005. In this case, try running the CHKDSK utility to fix the error. To do that, follow the instructions below:

  1. Right-click the Windows icon on your taskbar.
  2. Select Command Prompt (Admin) or Windows PowerShell (Admin) from the list.
  3. Type “chkdsk X: /f /r” (no quotes). Replace ‘X’ with the hard drive you need to repair, then press Enter.
