I have a weird problem with my Dell inspiron 1520 laptop. Just recently if i hit the mute button on my laptop my system will lock up. I can move the mouse but i can't click or type, if i hit CTRL ALT DEL the window task manager would come up but i can't do anything. I can even hit the windows icon and the start menu would come up but i can't do anything. Anyone ever had this problem before?
