Re: Inspiron 580 noise
Skyro, same thing happened to me. It sounded like a fan was overworking (likely video card), so I dialed down the resolution. The sound went away, but the picture on the ST2310 monitor looked terrible. So I pulled the box from it's cubby, and was going to open it to have a look, but was called away to the phone. When I came back the whirring noise went away? Turns out it wasn't getting enough ventilation at the rear, it sticks out a bit further from the wall now (4 inches), but the annoying sound went away. I think the fan was overcompensating for the lack of ventilation. regards.
