Computer Making A Loud Noise

Hey my comp is normally quiet, then it goes bonko's and makes a really loud noise as if its gonna blow. So i shut it off, restart it and its no longer there, but then a few hours later its back... any idea how to fix this or wat it is and is it hard to fix?

 

Open up the case and clean it out. Make sure all fans are ok and such, including cpu fan.

 

could be one of your drives dieing, or your cpu/case fan is unbalanced.

 

first guess is a cord is touching a fan, second, f'ed drive.

 

Happens with my PC all the time --;

It just means your fan is working harder to cool the PC.

 

^not always.. most fans should stay at a constant speed, unless they are controlled by hardware or software.

 

yeah, something is getting in the road of one of your fans therefore making a loud noise, but when you mean 'as if its gonna blow up' does it sound like a bomb is being dropped or does the sound get a higher pitch ?

 

LMAO.... explain the noise with more detail please.

 

If it sounds like an aeroplane, I'd clean out the fan or get a new one. My pc started sounding like an aeroplane and the psu blew up. Had to go buy a new one <3

 

lol or it may be that you are running it for to long. take a break and let it cool down

 

my cpu fan sounded like a screaming yeti, because a wire got stuck in it, and broke one of the fins. bought a new one, fixed...

 

maybe one of the fans is shot... one of my computers beeps all the time no idea why tho.

 

Depends what you mean by "it's gonna blow".
Either the smal vibrations that are hitting against the wall, or if it's a grindy sound, then all it is is a sign of your computer getting old.

 

^neither are good lol

 

it is grinding or just a loud humming
