Freezing problem resolved , but now there's no audio recognition.

Hello everybody.
I'm new to the forums as I must get help and I begin to give up any hope.

Anyway a few days ago I began having computer freezing problem , it just froze completely and the sound began buzzing , only re booting could restore the pc.
The freezing could happen again in a few minutes or in a hour.

The strange thing is that the next day I boot the PC ( after it was shut down for a lot of time ) the freezing doesn't happen , as if it just had over heats.

Yesterday I tried to update my motherboard drivers ( USB 3.0 driver and Realtek audio driver from the motherboard drivers ) , I updated the audio drivers as I suspected that the problem could be tied to the audio...

The freezing was completely fixed !

But there was other problem that happened , now that I updated the drivers the PC just won't recognize the headphones I plug in , I also say that the problem isn't from the headphones , they work.
When I install the motherboard audio driver it says that there is audio but not from the headphones and it won't recognize them even as un-plugged.

I'm afraid there's a problem with the drivers as I installed and re-installed many times.
Please help.
