    Could you describe the noise in more detail? Does the computer still function as expected?

Noise whistling

If the noise is a high pitched hum first make sure it is coming from the PC rather than some other device. Just turn everything off except the computer (including turning off the monitor) and see if the noise goes away. Now if you still hear the noise, turn things back on and turn the pc off for about 30 minutes. Then turn it back on. If the whistle is not present at the start but takes a bit to start -- a minute or two or more -- it is probably heat related. If it is immediate, it is probably due to some hardware failing.

If it's a heat problem and you can, turn the system off, remove the side of the computer and run it that way. If the problem goes away (and stays away) then take a can of compressed air and blow out all the dust and dirt you see in the box (again, turn it off when you do this) close it back up and test. If it doesn't go away, the problem may be more serious, needing attention by a qualified technician (to at least change the heat compound on the CPU and other places).

If the whistle is immediate and you are comfortable with it, put your finger in the center of each of the spinning fans to temporarily stop them. Stop them only for a second, not for more. If the whistle stops have that fan replaced. Finally, if the whistle is almost immediately apparent when you start the system then it is usually coming from the either the power supply or the hard drive. A replacement power supply should cost about $40. In most systems they are easy to change so it may be something you could do yourself. We charge $49.50 for the labor, just to give you a rough idea. If changing the power supply doesn't do the trick it's probably the hard drive. So back up your stuff and take it in to be redone....Hard Drives are generally around $70 and labor to redo the system $100.

I have a 06 Freestar that makes a whistling noise. Very annoying and random. I can't associate it with anything. Sometimes it doesn't do it at all but mostly it does. Never when stopped or going below...

LOL , We had this issue arise before and it turned out to be that when the audio guys at American TV installed the car stereo speakers in our door , they tore the plastic sealing membrane on the inside of the door under the door panel.
To locate the leak you will need a passenger with good hearing .
drive into the wind until the noise starts and have the passenger guess which door the whistling is coming from... remove the door trim panel and be sure the membrane is intact and sealed... pay close attention to the mirror area... as they are prone to leak and cause a whistle...

Hope this helped!

I have a 2001 Chrysler Town & Country Minivan. When turning the wheel either way, the car makes a horrible grinding noise and the steering wheeling makes a whistling noise at the same time.

i don,t know what the whistling noise is but it sounds like your cv joints may need to be looked at. the bearings in the cv joint maybe going bad.

Wind whistle noise

To determine what's making the whistle, try putting some tape over anything that might be causing it. I'd tape over any trim or moldings to try and find out where its coming from. You might try a wide roll of tape over the window edges, and trim points, if the whistle stops, take off a section at a time and recheck until it appears again, and you know what's causing it. Try to keep the tape flat, or you might create some new whistles! Let me know how you do. countrycurt0
