I can't turn off my screen on my Dell Inspiron R17?

This question is not answered

Hey all,

I have a problem with my laptop, I was busy with cleaning up my laptop(deleting unwanted software etc., weekly Virus scan and register clean-up) but today I was trying to press the button to turn off my screen(there's a row of three buttons one for a windows window to turn on and off wi-fi etc., the second calls Dell Support Center and the third one turns of the screen and lights up.) nothing happened. So I tried to turn of my screen with power saver(the third button for screen off will light up then, but after my screen was black and empty I didn't see the button giving it usual light, it was turned off..)

I use this button a lot since I really appreciate my privacy, does any of you know how to fix my problem? I am 100% positive it is a software problem, because when I turn my PC on it flickers like it always does. So the button is not broken.
