\nHow to Fix Error Code 0xc0000005<\/h2>\n
Below are several methods to help you identify the root cause and effectively resolve the error.<\/p>\n
1. Run System File Checker (SFC)<\/h3>\n
The first step is to check for any missing or corrupted system files:<\/p>\n
- \n
- Press Windows Key + X<\/b> and select Command Prompt (Admin)<\/i> or Windows Terminal (Admin)<\/i>.<\/li>\n
- Type the following command and press Enter<\/b>:
sfc \/scannow<\/code><\/li>\n- Let the process complete. If corrupted files are found, Windows will attempt to repair them automatically.<\/li>\n<\/ol>\n
2. Check for RAM Issues<\/h3>\n
Faulty memory modules are a leading cause of error 0xc0000005. Windows provides a built-in tool to check your RAM:<\/p>\n
- \n
- Press Windows Key + R<\/b>, type
mdsched.exe<\/code>, and press Enter<\/b>.<\/li>\n- Select Restart now and check for problems<\/i>.<\/li>\n
- Allow the tool to check your memory. It will report issues upon reboot.<\/li>\n<\/ol>\n
If issues are found, you may need to replace one or more memory modules.<\/p>\n
3. Update or Reinstall Drivers<\/h3>\n
Outdated or broken drivers can cause access violations. Be sure all your drivers are current:<\/p>\n
- \n
- Open the Device Manager<\/i> by pressing Windows Key + X<\/b> and selecting it.<\/li>\n
- Go through each category (especially Display adapters<\/i> and Network adapters<\/i>) and right-click to Update driver<\/b>.<\/li>\n
- You can also visit the manufacturer\u2019s website and download the latest drivers directly.<\/li>\n<\/ol>\n
4. Perform a Malware Scan<\/h3>\n
Malicious software may prevent applications from accessing necessary memory areas. Use your built-in or third-party antivirus software to run a full scan:<\/p>\n
- \n
- Open Windows Security<\/i> from the start menu.<\/li>\n
- Navigate to Virus & threat protection<\/b>.<\/li>\n
- Click Quick scan<\/b> or Full scan<\/b> for a thorough check.<\/li>\n<\/ol>\n

\n5. Disable Data Execution Prevention (DEP)<\/h3>\n
DEP<\/b> is a memory protection feature that can sometimes interfere with legitimate programs. Disabling it might resolve the error, especially if only one program is affected. Here\u2019s how to do it:<\/p>\n
- \n
- Press Windows Key + Pause\/Break<\/b> to open System Properties<\/i>, or search for View advanced system settings<\/i>.<\/li>\n
- Under the Advanced<\/b> tab, click Settings<\/b> under Performance<\/i>.<\/li>\n
- Go to the Data Execution Prevention<\/b> tab.<\/li>\n
- Select Turn on DEP for all programs and services except those I select<\/i>.<\/li>\n
- Click Add<\/b>, browse to the affected executable file (.exe), and add it to the exclusion list.<\/li>\n
- Apply the changes and restart your PC.<\/li>\n<\/ol>\n
Note<\/i>: Only use this method if you are sure the application is safe and not counterfeit software.<\/p>\n
6. Modify the Windows Registry (Advanced Users Only)<\/h3>\n
If you’re comfortable editing the Registry, you can try this fix\u2014but be very cautious<\/b>, as mistakes can severely impact your system:<\/p>\n
- \n
- Press Windows Key + R<\/b>, type
regedit<\/code>, and press Enter<\/b>.<\/li>\n- Navigate to:
\nHKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Windows\\AppInit_DLLs<\/code>\n <\/li>\n- Ensure the value for AppInit_DLLs<\/i> is empty. If not, double-click it and delete any value in the field.<\/li>\n
- Close the editor and restart your computer.<\/li>\n<\/ol>\n
7. Restore Your System<\/h3>\n
If the error started recently, use System Restore to roll back to a previous stable configuration:<\/p>\n
- \n
- Type
rstrui<\/code> in the Windows search bar and hit Enter<\/b>.<\/li>\n- Select a restore point before the problem began and follow the prompts.<\/li>\n<\/ol>\n
8. Perform a Clean Boot<\/h3>\n
Third-party software may be causing conflicts. To isolate the issue:<\/p>\n
- \n
- Press Windows Key + R<\/b>, type
msconfig<\/code>, and press Enter<\/b>.<\/li>\n- Under the Services<\/b> tab, check Hide all Microsoft services<\/i> and click Disable all<\/b>.<\/li>\n
- Go to the Startup<\/b> tab and open Task Manager<\/i>.<\/li>\n
- Disable all startup items.<\/li>\n
- Restart your computer. If the error is gone, re-enable services one at a time to find the culprit.<\/li>\n<\/ol>\n
9. Reinstall the Problematic Application<\/h3>\n
If the error occurs with only one specific program, reinstalling it may resolve the issue:<\/p>\n
- Under the Services<\/b> tab, check Hide all Microsoft services<\/i> and click Disable all<\/b>.<\/li>\n
- Select a restore point before the problem began and follow the prompts.<\/li>\n<\/ol>\n
- Navigate to:
- Under the Advanced<\/b> tab, click Settings<\/b> under Performance<\/i>.<\/li>\n
- Navigate to Virus & threat protection<\/b>.<\/li>\n
- Go through each category (especially Display adapters<\/i> and Network adapters<\/i>) and right-click to Update driver<\/b>.<\/li>\n
- Select Restart now and check for problems<\/i>.<\/li>\n
- Type the following command and press Enter<\/b>:
- Press Windows Key + X<\/b> and select Command Prompt (Admin)<\/i> or Windows Terminal (Admin)<\/i>.<\/li>\n
