The cpu is overheated.
I have almost the same problem with almost the same type cpu.
Probably the voices are because the cpu gets very hot,and when this happens the pc restarts or freezes and makes this noise.
You can see your cpu's temperature via bios or by installing speedfan.
As i remember the default temp for the noise to come out is 80c.
So you reach 80c every time it freezes.
I am not sure you will solve it the way i am gonna tell you,but give it a try.
Open the case,and there you will see a fan named Intel.
Unplug the cpu's fan 1st by turning left all of the 4 pipes.
Unplug the wire that powers on the fan.
Then push the pipes up with some force and gently.
Clean the dust from the fan's bottom and whatelse is there with a paper[gently].
Then use another paper to gently clean the cpu surface.
Then you will need some cpu's glue which you can buy on a computer shop.When you have the glue put very little in the middle of the cpu's surface.
And the last step:
Take the fan and gently push it down into the 4holes.
Make sure you push them down good.
Then turn right the 4 pipes.
Plug the wire that connect the fan.
Make sure the fan is not shaking.Try to shake it with your hand gently.
If it's stable and not moving too much you are ok.
Note:for the 4 pipes you will need a tool which name i don't remember.But you will understand if you do it.
The pipes,if the fan is properly installed must look on the fan's side.
