To use your PS3 controller wirelessly, you'll either need a PC with built-in Bluetooth compatibility or a Bluetooth dongle plugged in. You must plug in the controller before you can play wirelessly.
Before anything else, make sure your PS3 is disconnected because if you press the PS button, it will connect with and turn on the PS3, thus not letting you connect it to your PC. Then, connect your PS3 controller to your PC via the mini-USB cable to install the initial set of PS3 controller drivers
