What does it mean when PC starts making clicking/tapping sound?

Clearly, it’s not good. I can still boot up (Compaq Windows PC) usually, although not always. I'm pretty sure it's coming from the hard drive.

Sounds like it's time to get a new hard disk or computer. The next time you boot it up, make sure you do a full backup ASAP.

What you are hearing is computer morse code that means “spend some money and fix me.” Preserve all your data immediately and stop using it. Clicking sounds usually indicate bad heads in your hard drive. If you continue to use it, the problem will just get worse.


Hopefully we can rule out the NSA. :)


Interestingly, there's an entire website devoted to hard drive clicking sounds. It lists more than a dozen possible reasons, along with links to information for each possibility.


Good luck with it.
