Problem with Windows

Hello Majorgeeks! Let me start off with my problem. I've recently reinstalled my windows (Windows7 Ultimate SP1 64-bit). When I try to run games (they're not pirated!!!) I get a message saying: The application was unable to start correctly error(0xc000007b). Click OK to close the application. Now I have tried alot of things I reinstalled DirectX, .Net, used an all in one program, I have also tried replacing the .dll files in system32 that are supposed to cause the problem. Those .dll files were missing when I installed Windows (didn't happen the last time). But nothing seems to work. Any help would be greatly appriciated!

Here are my PC's specs:

Proccessor: AMD A8-5600K APU
RAM: 8gb
System type: 64-bit

Cheers!
