Having problems with your HP Pavillion s7420n PC Desktop ?

At random times, my computer makes a rhythmic clicking noise. During the event the screen freezes up, and sometimes it stays locked up. At other times it functions just fine. What is the noise and is it dangerous?

Answers :

A methodical rhythmic clicking sound could be coming from the hard drive as it is having trouble reading a particular sector.

I would highly recommend that you backup your data and replace the hard drive.

How, if possible, open up the side of the computer and when the clicking starts, lay your palm/fingers on the side of the hard drive to see if you can "feel" the clicking to either confirm or not that the noise is coming from the hard drive.

Good luck
God Bless
