Hi. Disable your internet card, and other background programs like windows updates, virus/adware scanners, etc... The fastest computer will get clicks if these programs are running or checking for updates.
Usually the internet connection is the biggest cause of clicks especially wireless connections. Go to Network and sharing center, click change adapter settings. Right click on your device that connects to the internet and select disable. When you want to go back on the internet, right click on it and select enable.
