I have w3115 desktop computer.The cooloing fan is loud.How can i quiten it down?

The screaching is probably a drive belt not the fan, with engine running open hood and rev engine, if you hear the noise spray some WD 40 onto the alternator belt, it should quiten it, if it does then replace the belt

find this.

Have you installed the Audio, Chipset, VGA, drivers ????

sounds like a bad power supply... get one from newegg.com they are easy to replace, it will only plug in to the place it is supposed to.... check wattage out put and get same or higher

Use DIMM RAM memory for eMachinesW3115.

Firs thing you need to do is to find our why they are running full speed. My guess is that your computer is dirty inside and it is overheating, thus causing the fans to run full speed trying to cool it off. Disconnect everything from the pc and take it somewhere to clean it out. Remove the side panel an use a can of compressed air or an air compressor to blow all dust out the interior of the pc. Pay close attention to the heat sink on the processor and the cooling fans. When blowing around the fans hold the fan in place with a pencil to prevent it from spinning as this might damage the fan. You need to clean out the inside of a pc sitting on the floor every 6 months. If you have cats or dogs that shed living inside then every 4 months. If it is sitting up high and you have no animals then every year may be good enough.

Hi,
It's not normal for the fan to be loud, what makes them loud is either a build up of dust on the fan blades or the bearings are going on the fan itself.
If the PSU is working fine then you can replace the fan itself from an identical PSU. It does mean taking the PSU out of the computer and fitting the fan yourself.
Alternatively you can purchase another PSU.
