You have to have a tech check it out.
I've had a Dell Inspiron 15 3000 series laptop computer which I received from my brother almost 3 months ago and everything has been working fine but tonight while surfing online for the first time this laptop made the loudest noise; I've never heard anything like it before kind of noise; like something was hung up or locked up kind of noise and the only way I could make the noise stop was to totally shut the computer down.
The noise came from the lower left corner of the computer. There's a DVD burner on the right side but this loud noise wasn't coming from there; in fact I haven't used the DVD yet. Could this noise that I'm hearing be a fan related issue? I don't look forward to calling Dell's tech support for assistance but if it happens again I will do it.
