My computer gets louder when its doing high processing, i think. Like if I click and hold the X to close IE, it gets louder....sometimes when I scroll and load programs too...WTF is going on??? Is my power supply stressing?? Are the Fan speed changing? I have no idea. I have a CasEdge 3400S case with 250W PS. The specs of my comp are below. Any info on what could be causing this is appreciated.
