Last time I started laptop I heard some clicking sound coming from hard drive. I was not paying attention on it and Windows started correctly and I worked for few hours. But then I also heard clicking sound and this time computer restarted by itself. I have tried to start Windows again but I can only hear clicking noise from hard drive and I can not use laptop any more. How can I repair hard drive on laptop?
I hate to tell you but you can not repair hard drive on laptop. Problem is that your hard drive died and you should by a new one. You can install it by you own easily. Just unscrew bottom of the laptop (and, eventually, keyboard because some laptop models require this step to access hard drive) disconnect old drive and connect new, working one.
