There's something wrong here. It was yesterday when I turned on my computer, but it stopped on the starting Windows screen. I waited for 4-5 minutes but nothing happened. Windows starting screen was still there in front of my eyes. Then having no other option it rebooted the computer system again and stopped at the same place again. I consulted on of my friend, he advised me to start computer in safe mode. I did so, but nothing changed. Still the problem was on. I don't know what's wrong with it? Can you help me? Is there any problem with my hard disk or operating system?
