Help Me Find the Noise
I have a PC in my family room that I leave on all the time. A couple
of months ago it began making a noise. It's a noise similar to what a fan in a computer might make when it's dieing or slightly touching something as it spins. There are times when the noise stops. And there are times when the noise sounds a little bit harsher (as if the fan was clipping more of what it was hitting). But for the most part the noise has stayed the same since it first started. This PC houses two CD drives, one hard drive, and one floppy. Yesterday I had had enough of the noise. I replaced the power supply thinking that it's fan had the biggest chance of being the culprit. The noise persisted. I replaced the hard drive. The noise persisted. I pulled the plug on one of the CD drives. The noise persisted. I pulled the plug on the other CD drive. You guessed it ... the noise persisted. What else could be causing the noise? |

What else could be causing the noise? Does your CPU have a fan? Is there a fan anywhere else in the case? I've had to replace CPU fans after they went bad. I've also had to add washers to a CPU fan mount when I couldn't get the bolts tight enough to keep the fan from rattling. If that doesn't work, you'll need my 1992 Micro House Encyclopedia of Main Boards, for which I'm trying to find a home. Stack all four volumes in a pile between you and your PC, and you won't notice the noise as much. Louis Krupp |

You haven't told us about ALL the moving parts in the system, or have you? Leave the case open, take a piece of hose or a straw and hold it to your ear, and move it around to get a fix on the noise source. |

What else could be causing the noise? very possibly the cpu fan this may sound funny but it's not a joke: put a small rubber tube in your ear and use the other end to "snoop" out the noise... it really works! |

Or the cardboard tube at the center of a empty papertowel package works too. |

Noisy PC ...
This PC houses two CD drives, one hard drive, and one floppy. Yesterday I had had enough of the noise. I replaced the power supply thinking that it's fan had the biggest chance of being the culprit. The noise persisted. I replaced the hard drive. The noise persisted. I pulled the plug on one of the CD drives. The noise persisted. I pulled the plug on the other CD drive. You guessed it ... the noise persisted. What else could be causing the noise? What's left? Floppy, CPU heatsink, northbridge heatsink, video card, case fan(s)... You haven't told us about ALL the moving parts in the system, or have you? Well, I guess I'm not sure. I don't believe the CPU has a fan. It's an older PC. Does the floppy have parts that move all the time or only when using it? I don't believe the video card has any moving parts. Does your CPU have a fan? Is there a fan anywhere else in the case? I don't believe so. Thanks for all the tips everyone. I'll put some more time into finding the source of the noise when I get some more time. |
