Is my AMD FX-4300 working properly?

[hookIN]

So I've had my computer for a while now, and I believe my processor is not working properly.

Almost every game is play gets more FPS when I disable the first core (0) with Task Manager, some really old games like Counter-Strike 1.6 run extremely fast with all of my cores on and I need to turn off most of them to get it to run at normal speed. (It's like having speedhack)

I recently tried streaming, and all audio is playing faster than normal (like playing music with double speed) and I think my processor causes this?

Does anyone know anything about this issue? Or is the reasoning completely different?

Here are my computer specs:

NVIDIA GeForce GTX 750 Ti
AMD FX-4300 Quad-Core Processor
8GB's RAM
AsRock 970 pro3 r2.0

Does your operating system recognize the correct CPU in Control Panel > Device Manager > Processors?

Older games frequently run too quickly because they weren't coded with modern CPUs in mind. The programmer assumed a maximum CPU speed and coded around that assumption.

There are often patches or special .exes available to download which allow older games to run correctly on modern hardware. You could also try right-clicking the .exe of the programs you're running, select Properties > Compatibility and select Run in Compatibility mode for... and try a range of Windows OS versions to see if you get better results.

My theory is that if your PC isn't recognizing the right processor in Device Manager that your CPU might be using its Turbo Core feature constantly. This will result in erroneous clock speeds and strange program behavior, such as the OS being out of sync with the CPU clock frequency, which can manifest as music playing too quickly, games running very fast etc.
