My computer makes some sound like "Rmmm--" and keeps going, sometimes it just stops for 3 seconds then goes again.. Please help me, I cleaned out the dust from inside, so that's not the problem, and it's not overheated at all.
If you have fan in your computer ( most do ) check for anything that might be clipping it. Also to check your drives, I would suggest getting someone more computer hardware friendly before taking them out and what not. Its also possible that a fan in your PSU is hitting something.
