[SOLVED] Loud weird noise coming from gt5620 desktop

[cyborgjustan]

There is a weird noise coming from my gateway gt5620 desktop, when I push the power button, it boots up perfectly fine, but I want to get rid of the noise if that's possible. Please help
Btw: I have no optical drive

Take the side panel off and look inside. Odds are its a fan thats dying, or has a wire or something touching it.

Use your ears to try and figure out whats making the sound.

While you are in there:

Remove the mains connector from the PC.
Vacuum clean thoroughly, but dont allow you suction pipe to damage anything.
Do NOT play with fans speeding up with vacuum suction, it will destroy the fans.

Describe the noise a bit further. Is it a beeping noise or a whirring noise? If it's a whirring noise it sounds like something is obstructing one of the fans inside.
