Computer Makes a Loud Humming Noise.

by PinkGlitterFaery / November 5, 2003 11:42 AM PST

I have a HP XE783. It has always made this really annoying loud humming noise. Does anyone know what it is and how to stop it? I was thinking it may be the fan???

Most noise is from a bad or old fan with dust build-up. Remove or open the clam shell case(yours?) and see where the noise is coming from. Now is a good time to inspect as well as clean the innards. The power supply is another fan source but any fan can be a noisy one. Also, check to see if any *reasonace* from metal vibrates the hum or similar, if so, tighten or place some wieght there to help control reasonce. Sad -----Willy

So you've had this problem from the start, correct? I agree with what willy has said. I'd suggest opening up the case and sticking your head in there and attempt to find out exactly what the source is- sometimes feeling all over the case can give you a hint from the vibration you feel. Do you have a relatively high-end video card? This is often the source of noise- really not much to do about this. I've seen stuff you can put inside a pc case to dampen sound, but I personally think this would interefere with air-flow which would increase the heat inside- not a good thing. If you do find dust, get some compressed air and blow it all out- not only on the fans, but *everywhere*. I blew a soundcard because of dust build-up (had case open for a long time dust further insulated what I think is called a capacitor). Main thing I wanted to point out is the video-card, assuming all things are firmly screwed, and no dust- I've seen/heard some really loud vid cards. Good luck.
