Since last night my computer has been making this really weird sound. Kind of like a revving sound. I'm not sure what it is. I have an eMachines computer and this has never happened to me before. Anyone had this experience before and may know whats up with it? On a side note: I saw the stickied topic about eMachines PSU's, and yes I think I need a new one. My computer crashes (often), and some mild things, and some people and forums have told me to get a new PSU, so anyone know a good PSU brand to get? I'll probably buy one from TrigerDirect or NewEgg, just need to know a good brand.
