dual core

I have a question. I am going to stop my dual core to play a game, Do I need to do anything after I stop playing the game ... does it just stop it for the game when I go into the task manager and stop it for a particular game?

Start the game and then enter Task Manager (Ctrl+Alt+Del). Find your game on the applications tab and Right click it. Choose Go to Processes, and limit it to a single core.

does it just stop it for the game when I go into the task manager

Yep -
