Issue: How to fix Application error 0xc0000005?
Hello. Recently I have been bugged by an annoying error that prevents me from watching videos as they have no sound anymore. The pop-up says it's “Application error 0xc0000005.” Is there anything that can be done about this? I am using my computer just like I used to before, so I don't know why this started happening… please help me.
Application error 0xc0000005, otherwise known as Access Violation error is a broad problem and usually appears when users try to open various applications on Windows operating systems. It prevents them from doing so, as all they can press is “OK” which stops the program from being run in the first place.
Nevertheless, some users reported that 0xc0000005 can be related to multiple different programs, or that it pops up when trying to use built-in Windows features, such as Windows Media Player.
The application was unable to start correctly (0xc0000005). Click OK to close the application.
The root cause of the 0xc0000005 error is that some component within the system is preventing the application from starting correctly. However, there are multiple reasons why the issue might show up, including corrupted system files, broken Windows registry database files, malware infections, broken hardware (usually RAM), Data Execution Prevention (DEP) feature, security software, faulty drivers, etc.
Due to the nature of the 0xc0000005 error, it can be extremely frustrating to users, and might even prevent them from using most of the installed applicaitions on the Windows machine, prompting a full reinstall of the system, which might be extremely time consuming.
