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 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 are pretty important, as i recently installed Bioshock Infinite but it says I need to update my Video drivers as well as DirectX in order to play, but whenever i try to download it, it instantly becomes unresponsive. 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.
