Windows 7 .DLL File Error, cannot open certain files/programs

[Rfalke8]

This has been going on for a couple months, and it hasn't gotten in the way but now it is as it's preventing me from opening certain files and games i want to use, such as Skype, and games like Bioshock Infinite. Whenever i start up my computer or open specific programs, it says : "C:/Windows/system32/d3d11.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support." There's also an issue where if this doesn't happen, the program will instantly not respond forcing me to close it. I've tried installing numerous programs that would help fix this, but whenever i try to open them, it instantly doesn't respond. Programs i can recall instantly becoming unresponsive are Skype, Catalyst Control Center, and DirectX which whenever i try to open certain games like Bioshock infinite, it says my drivers are out of date and need to be updated, but i cannot open Catalyst Control Center without it becoming unresponsive, so i cannot update my drivers! I'm not sure what to do, i'm not really good with computers either and i'm hoping someone out there knows what went wrong and can help me. Thanks.

It seems like there are issues with system files related to DirectX and possibly your graphics drivers that are causing programs to become unresponsive or fail to launch. Here are a few steps you can take to troubleshoot and potentially resolve these issues:

Reinstall DirectX:​

1. Download the Latest DirectX:
   • Visit the official Microsoft DirectX End-User Runtime Web Installer page and download the latest version of DirectX.
   []Run the Installer:
   • Install DirectX on your computer to ensure that all necessary files are up to date and properly installed.

     Update Graphics Drivers:​

   []Using Device Manager:
   • Press Win + X and select "Device Manager."
   • Expand the "Display adapters" section.
   • Right-click on your graphics card and select "Update driver."
   • Follow the on-screen instructions to update the driver.

     System File Check:​

   []Run SFC Scan:
   • Open Command Prompt as an administrator.
   • Type sfc /scannow and press Enter.
   • Let the System File Checker scan and repair any corrupted system files.

     Reinstall Specific Software:​

   []Reinstall Catalyst Control Center:
   • Uninstall the current AMD Catalyst Control Center.
   • Download and install the latest version from the AMD website.

     Malware Scan:​

   []Perform a Full Scan:
   • Use reputable antivirus software to perform a full system scan to check for malware or viruses that could be affecting system files.

     System Restore:​

   []Restore Point:
   • Consider restoring your system to a point where you did not encounter these issues.
   • Press Win + R, type rstrui, and hit Enter to launch System Restore. If these steps do not resolve the issue, you may need to seek additional help from a professional technician or Microsoft support to diagnose and fix any underlying system issues that could be causing the problems you are seeing with DirectX and other applications.
