sfc /scannow
3. Allow the System File Checker process to complete.
Afterward, attempt to run the application that was previously showing error 0xc0000005. If the issue persists, proceed to the next method.
Method 4: Inspect Your BCD (Boot Configuration Data)
If your computer is experiencing hacked or infected files, potentially influenced by a virus or malware, carefully examining your BCD (Boot Configuration Data) is necessary. Specifically, watch out for files like xOsload.exe, xNtKrnl.exe, or/and OEM-drv64.sys, which may indicate tampering aimed at bypassing Windows activation.
Method 5: Disable DEP
The application error 0xC0000005 is frequently attributed to Data Execution Prevention (DEP), a security feature introduced by Microsoft in Windows SP2 and continued in later versions. DEP aims to prevent code execution from non-executable memory segments. To address this issue, you can disable DEP by following this guide.
Method 6: Faulty RAM Memory
The application error 0xC0000005 commonly arises from defective RAM memory. If you’ve recently encountered this error after installing new RAM, it’s likely the culprit. To investigate, try removing the new memory to see if the error subsides.
Before proceeding with memory removal, remember to:
1)Power off your computer and disconnect all cables (power, network, etc.).
2)Remove the battery (if applicable for laptops).
3)Ground yourself to discharge any static electricity before handling the memory.
If removing the new memory doesn’t resolve the issue, consider testing your computer’s RAM for potential faults.
Method 7: Utilize Rkill
Rkill, a tool developed by BleepingComputer.com, terminates known malware processes, enabling standard security software to clean your computer effectively of infections. Upon execution, Rkill terminates malware processes, rectifies incorrect executable associations, and resolves policies hindering the use of certain tools. After completion, it generates a log file displaying terminated processes during its operation.
Additionally, if you suspect a virus or malware to be the cause of the Application Error 0xc0000005, it’s advisable to scan your system using updated Anti-Malware or Antivirus software. Microsoft Security Essentials, an official and free Antivirus program by Microsoft, is recommended. Alternatively, utilize third-party Antivirus or Malware scanners to remove malicious programs from your system.
In light of this, scanning your system using antivirus software is crucial to promptly remove any unwanted malware or viruses. If you lack third-party antivirus software, rest assured that you can utilize the built-in malware scanning tool provided by Windows 10, known as Windows Defender.
Method 8: Temporarily Disable Antivirus
Antivirus programs have the potential to impact the executable files of various programs. To troubleshoot this issue, consider temporarily disabling your third-party antivirus program to determine if it’s the source of the problem. However, please be aware that disabling antivirus programs can expose your computer to potential threats when connected to the internet.
