Computer is always loud

[Stitch]

For ages my computer has been making really a really loud noise the whole time it is on. I'm guessing it's the fan because thats what it sounds like. Is there anyway i can stop it because i can sometimes hear it halfway accross my house.

See if the fan has any dust on it, before mine had dust covering the far and it was really loud, just clear the dust and it should be fine.

What sort of noise is it?

It must be the fan yes, try taking it out and see if that helps

I kinda cleaned mine today. I got the keyboard & the back off my laptop, then couldn't work out how to get to the fan. I then got my mum to get some compressed air, now then fans working properly, and no sound

My downstairs also had the same problem.
If you leave it, the motherboard will overheat, so just take it out and clean it, dust it and maybe put some of the lubricant stuff onto it.

Easy problem to fix:

1. Take a vaccum cleaner to the back of the computer where the fans are and suck away.

2. If no joy then buy compressed air from a hardware store. Take the back off the computer and clean everything.

3. Also check your computer isn't leaning against a wall as it will be blocking the airflow out of the machine.
