Screeching noise from computer

[breakurjea]

I just recently built a new computer and the first time i turned it on, it started making a really loud screeching noise. The noise continued as long as i had my computer on. ANy ideas why?

I'd open the case while it's on and have a listen to see if you can isolate the location. You can carefully touch your finger to each fan's rotating center to temporarily stop it from spinning to see if it's a bad fan. Also check if there are any stray cables getting in the way of fan blades.

- Is it coming from the speakers or is it a mechanical noise?

- If it's mechanical it's either a fan, a hard drive or a CD-Rom drive. Process of elimination: disconnect all your drives and see if it still makes the noise. Check each of your fans.

That's a common noise when the lead hamster falls off the treadmill.
