I own a Dell pentium 4 processor 520 (Dimension 4700 series) with 2.8ghz that has been putting out horrible static through the speakers. I've tried unplugging and rebooting and I believe it's the subwoofer. A friend recently gave me a pair of speakers (harman/kardon) to try. Do I need a subwoofer to go with these speakers? My computer came with speakers attached to a subwoofer.
I need help!!!
I reversed my fan last night, and I believe it solved the static problem. Only time will tell, I suppose. When I first used the computer after flipping the fan, both fans suddenly were extremely loud and noisy and rattling. But now that I have had my computer running for about an hour or so, they got quieter and quieter and now are completely silent. (I can still feel the air blowing though). I suppose it realized that it wasn't going to overheat anymore and didn't have to run the fans so hard!
I consider my problem solved. I'll be back if it changes, but so far I highly recommend flipping the fan to run the other way. It was really very simple to do once I understood how to disconnect and reconnect all the parts! If anyone needs step by step instructions and they can't find them, please email me at timm100 [at] mail [dot] chapman [dot] edu. I am very new to this whole internal computer thing myself, so I know how confusing it can be!
Dell 4700 Check the video card fan. Had one that was full of dust..Cleaned it and moved the sound card away from the video card.. this fixed my problem.

Thank you. Problem fixed!
i've got this problem with my dimension 4700, and i've read several places that overheating of the CPU can cause static in the sound. several people have said that when they cooled their CPU more, the static went away. apparently 4700s have a heat problem, especially went in a small area or pushed against the back of a desk or wall. dell sent some of them out with an unusal fan configuration that they claim is intentional, but many people have fixed the heat problem by reversing the lower fan on the back of the unit to blow out of the box instead of sucking in. give it a google and you'll find a couple of step-by-steps for doing it yourself... I'm going to flip mine around sometime this week and see if it solves my static problem!!!
