Creaking door noises
 

Good afternoon
I wonder if anyone can tell me what would create "creaky door noises while using the computer and just as often I hear crashing noises. My Dell computer is less than a year old,my old computer did it as well. Should I be worried?

There are a few things that could cause the creaky noises....the most common would be a fouled bearing on one of the fans. This could be from excessive dust build up or just a faulty fan....even new ones can be bad.

Other clacking/clicking sounds are sometimes caused by the harddrive...

The chattering is a general sign that there may be impending troubles

I would open the side of the computer and try to locate the noise and what is responsible and thus replace/repair the problem.

Ooooooooooooooh spooooooooooooooooooooooooooooooooky...
