It is noising and working slowly. What should I do?

When I press the power button of my Pc, it makes noise. I am sure the source of this noise is Hard Disk Drive. Now my pc is working slowly from the startup. What should I do?

Are you sure, the source of noise is you HDD? Cooling fan cam makes noise sometime. If the source is HDD I am sorry to say, your HDD is going to die. You only can change your Hard Disk Drive. Some suggestions for you:
1. Create a backup before changing your Hard Disk Drive.
2. If your Pc is under warranty, send it for repairing.
3. If warranty is over, then buy one and replace.
Hi Mitu
There are two possible solutions to your problem. Either you change your Hard disk drive or you repair your hard disk.
There is a software, a diver booster that boosts a hard disk drive. It is packed along with Advanced system care. It scans your PC and fix any errors and it has two modes, game mode and work mode.
