Asus does not respond

okay i have a laptop and its a Asus version. normally you log into your computer do whatever you gotta do. so when i try to click one of the icons on the desktop screen or in the start menu and it does not show like the internet page or whatever i will click on, it just makes a sound like i am clicking something wrong. i have no idea what is wrong with it but i would be really grateful for some help.
