Do you Hear Clicking / clanking Noises ?

If you're hearing clicking sounds coming from your computer it is suggested that you immediately power off the machine, and take it to a local computer repair shop for analysis. The longer you leave a machine powered on with a failing hard drive clicking, the more likely it is that data recovery will be more difficult, or sometimes not possible.
