I have a 8400 Dell and it was super quiet when I first got it. I keep it on 24/7 and sometimes shut down when it gets slow. I've had it for a year now. But I noticed that now it is getting a bit louder. I dont know if it is the fan or HD.

clean the dust from your fans, they are probably in need of some cleaning / lubing. if it's a hum, it's typically your fan, if it's a vibration it's typically your hard drive.

i sprayed WD-40 into the fan one time and it made it pretty quiet again... haven't had any problems with it since, and this was like 3 years ago

crisco on the processor ALWAYS does the trick! [/old thread reference]

Ummm...you tried opening the case yet? Love to help you out ... but its kinda like telling me there's a noise coming from the engine ... and you have yet to pop the hood and isolate the noise.

find the fan making the noise.

unscrew it from whatever its on.

clean it, wd-40 it, put it back in.

Hey, how exactly is a rainbow made? How exactly does the sun set? How exactly does the posi-trac rear end on a Plymouth work?
