My computer sounds like an airplane talking off, whats wrong with this thing?

Question

I just turned my pc on & makes a horrendous racket like a plane taking off. The sound usually lasts 3 mins then gets quiet. I cleaned it & checked the fans & all looks fine from the outside. It runs ok, not perfect but ok...why does it make all that noise & what can I do to stop it?

Answer 1

you need to get a new fan or clean off the one in your pc

Answer 2

Ooooh, i got that with my old compy, so 2 shut it up I put a heavy book on top of it.  Not good, because it overheated!!! >:P

Answer 3

Some motherboards can regulate the fan speed and maybe noise. You could check in the BIOS... Check for QFan or Fan Speed Settings or something

Answer 4

Did you check your optical disk (CD, DVD) drive. I  think some clogs have been jammed there which makes the sound when you boot your pc because when we start the computer, l the drives are initialized.
