For a while I've had a problem with my PC making a strange pulsing sound, around every second or so, and it's hard to describe. It sounds like the fan gets louder during each pulse, as if a person was turning the volume up and down. The thing is I can feel the pulsing through the PC desk, and on the PC itself. However, when I remove the side section of the PC case, the pulsing sound goes and there is just a constant fan noise. I don't really want to leave the case off because it will get dust in it, and it doesn't look like anything is pushing against it or anything. Any ideas? ]]> Cases ianpwilliams http://www.pchelpforum.com/cases/78912-weird-pulsing-sound.html
