Hello some of you would play games that use punkbuster anti cheat program, Even when you don't play the game the proccesors are running and eating up your CPU and memory.. For nothing!
Here is a solution that I use and also works so that punkbuster will only start up when you run a game that needs it.
1: Start -> run -> Services.msc
2: Find PnkBstrA , PnkBstrB <-- Or similiar, Sometimes depends on the game.
3: Right click -> Properties
4: Start up type -> Manual.
Hope this helps!
