I need some help here. Yesterday I was installing Avast on my laptop. While the program was scanning my entire system for issues, from the boot-up screen, my laptop just shut off. It's been known to do this before, especially right in the middle of something important, of course, but now the damn thing will not turn back on! The power light goes on, I hear the fan going, but nothing else. Windows will not open. Actually, nothing opens in the computer... My screen stays black, no power to usb's or network card either
Is there a way to boot this thing up? I am totally lost here. I do apologize if this is the wrong forum. I couldn't find one for laptops so I figured I'd go to where the masses are....
PLEASE SOMEBODY HELP........

Thank You, MB
