strange noise

I cant quite tell from where specifically, but my tower has been making subtle rattling noises. It's hard to describe, it's somewhere in between a rattling and a buzz. I think I keep my computer pretty well maintained, but this confuses me, heh. I have a fan mounted in the lower front of my tower which is turned on manually, when I do turn it on the noise stops. I would leave the fan on constantly but I leave my computer on overnight often and it is a hard choice picking out which noise is least bothersome, the fan or the rattling, haha. I was just wondering if anyone knew what this was and how I could fix it? Thanks

Re:strange noise

The likely causes are fans & HD.

Clear all your fans from dust and do a Scan Disk to check if your HD has any bad sectors.

Or go to the HD manufacturer's site and run the diagnostic test.

My computer does the same on occasion. You may have a different problem, but in my case, it is just the removable side panel vibrating.
Easy check is just place your hand on the sides of the computer, and if noise stops, then tighten, or loosen the panel screws.

I was thinking along the lines of Ray before I read his post, but I was also thinking of something *inside* the tower- may be worth tightening some screws- espicially the case fans. Now that I think of it, you say the sound goes away after turning on the front fan- could be that that's 'rattling'? btw, I once had a rattling sound in one of my old systems, and tightening the screws on my hardrives seemed to have cured the noise problem. Good luck.

Re:strange noise

Seriously suggest leaving the fan on when the system is on. Better to hear the fan running than overheating and frying the HD (a real pain.)

In any case, if this HD noise is something new I'd suggest having the system examined. The HD could have a foot in the grave.

Re:strange noise

Remove cover and follow you ear. It's usually the other way around, a running fan is noisy, not off. I suggest placing some damping material to help quelch the sound source either from resonance or simple metal rattling. Material like fabric softner sponge type sheets does great or similar. Too tight screws can also be troublesome as they too readily aloow any rattling to easily transmit, just snug and even there you can use damping material. Plastic items than snap-in area also a source, make sure they're fully seated or not cracked.

good luck -----Willy
