Why does our computer make a slight noise when playing with the AVA (King of Battlefield) chassis?

Oh, that's normal. That kind of map game is expensive. You have to explain your configuration. There is basically no dual core.

3.0GHZ is no good, the graphics card seems to have to be pinched at 88, otherwise it will get stuck. As you said, this situation is average.

It may be that your CPU is overheated and the radiator power automatically increases to the maximum. This is the vibration generated when the fan is running. It may also be that your radiator is too dusty and has poor heat dissipation. What you said later may be caused by dust. Clean the computer. If not, you have to bid farewell to the game or upgrade the configuration.
