Answered by Antonio Sutton

Access violation 0xc0000005 is a common error that occurs when a program tries to access a memory location that it is not allowed to access. This error can be caused by a variety of factors, including software bugs, faulty hardware, or corrupt system files. Fortunately, there are several steps you can take to fix this issue.

1. Update your software: Access violation errors can often be caused by outdated software. Make sure that all of your programs, including your operating system, drivers, and applications, are up to date. This can help to resolve any compatibility issues that may be causing the error.

2. Check your hardware: Faulty hardware can sometimes cause access violation errors. Make sure that all of your hardware components, such as your RAM, hard drive, and graphics card, are functioning properly. You can run diagnostic tests or consult with a professional if you suspect that hardware may be the cause of the error.

3. Scan for malware: Malware infections can also cause access violation errors. Run a thorough scan of your system using a reputable antivirus or anti-malware program to check for any infections. If any malware is detected, follow the recommended steps to remove it.

4. Repair corrupt system files: Corrupt system files can sometimes trigger access violation errors. To fix this, you can use the System File Checker (SFC) tool, which is a built-in Windows utility. Open the Command Prompt as an administrator and type “sfc /scannow” without the quotes. This will scan your system for corrupt files and attempt to repair them.

5. Disable DEP: Data Execution Prevention (DEP) is a security feature in Windows that can sometimes conflict with certain programs and cause access violation errors. You can disable DEP for specific applications by following these steps:
A. Press ‘Windows + R’ to open the Run dialog box.
B. Type “sysdm.cpl” without the quotes and hit Enter.
C. In the System Properties window, go to the Advanced tab.
D. Click on the “Settings” button under the Performance section.
E. In the Performance Options window, go to the Data Execution Prevention tab.
F. Select the option “Turn on DEP for all programs and services except those I select”.
G. Click on the “Add” button and browse for the executable file of the program that is causing the access violation error.
H. Select the file and click ‘Open’, followed by ‘Apply’ and then ‘OK’ to save the changes.

6. Fix registry issues: Registry problems can also lead to access violation errors. To fix this, you can use the Registry Editor to modify certain registry values. However, it is important to note that modifying the registry can be risky, so it is recommended to create a backup before making any changes. Here’s how you can fix registry issues:
A. Press ‘Windows + R’ to open the Run dialog box.
B. Type “regedit” without the quotes and hit Enter to open the Registry Editor.
C. Navigate to the following path: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_Dlls.
D. Double-click on the “LoadAppInit_DLLs” value and change its value from 1 to 0.
E. Click ‘OK’ to save the changes.
F. Close the Registry Editor window and restart your system to apply the changes.

It is important to note that access violation errors can be complex and may require a combination of troubleshooting steps to resolve. If the issue persists, you may need to seek further assistance from technical support or a professional computer technician.
