In my office there is a laptop dell inspiron 1420 with HD of 100GB of space. The computer is about a year old, and the hard drive has a weird and annoying ticking sound. The ticking sound starts after the pc is on for 15 minutes or so, but when it starts it does not stop.
We ran the dell hardware diagnostic and it reported the hd to be OK and pass all tests. We already did a full backup of the important information just in case it is the hd that is failing. Just wondering why it's making this noise (other than the obvious "it has a problem").
