Hi.

As Dean said, if the humming noise is always present even with the fan spinning at low RPM, replace it. If it's only loud when booting it might be normal ; some computer's BIOS spin the fan very fast when booting and when the Operating system or preset parameters take over, they gradually lower the speed. By the way, unplug the fans one at a time to find which one is causing the noise. If it is a case fan they cost only a few bucks, if it is the CPU fan it is a bit more expensive but aftermarket cooler can be found for around 20$. If you need to replace the CPU cooler, make sure you clean the old thermal paste and apply some fresh one. For a tutorial how Youtube is your best friends ;)

The fan is a cheap "bushing" fan and there is no repair once the bushings go. The only "fix" is to replace the fan. Sorry, but it's your only option.

SOURCE: PC SHUTS DOWN MONITOR AND FAN

Hi Brandy19960,

Thanks for the posting in FIXYA.

Please do the following steps:


Step – 1

Right-click on My Computer, open Properties, click the Advanced tab. Under “Startup & Recovery,” click Settings. Under “System Failure,” Uncheck the box in front of “Automatically restart.”



Step - 2


To change the setting, click Start --> Run--> type GPEDIT.MSC, click OK.

Drill down to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options.

In the right pane, find “Shutdown: Clear Virtual Memory Pagefile.”

NOTE: Since someone actually has to have set this policy, the problem will be pretty rare, but is worth mentioning. However, Forum participant “roadrunner” reported that the personal security app Privacy Eraser automatically enables “Clear virtual memory pagefile,” and, therefore, may be the cause of a slow shutdown.



Step - 3

When Windows XP won’t powerdown automatically, the APM/NT Legacy Power Node may not be enabled. To enable this, right-click on the My Computer icon, click Properties | Hardware | Device Manager | View. Check the box labeled “Show Hidden Devices.” If it’s available on your computer, there will be a red X on the APM/NT Legacy Node. Try enabling it and see if this resolves the powerdown problem (Tip from Terri Stratton). Or, to check the other side of the APM/ACPI coin, open the Power Options applet in Control Panel. If there is an APM tab, make sure the “Enable Advanced Power Management Support” box is checked.


Step - 4
----------

Try a Shutdown shortcut -


For a shortcut to RESTART Windows XP:
SHUTDOWN -r -t 01

For a shortcut to SHUT DOWN Windows XP:
SHUTDOWN -s -t 01

Step 5
---------

WORK-AROUND: Disable power management for your USB hub: Open Device Manager (click Start, click Run, type DEVMGMT.MSC, click OK). Double-click to expand Universal Serial Bus Controllers. Double-click USB Root Hub. Click Power Management. Uncheck the box “Allow the computer to turn off this device to save power.” OK your way out

Step – 6
-----------
Click on the Start button.
Select Run from the menu.
In the run dialog box type “msconfig”.
Click OK.

Once in the msconfig utility select the startup tab. In the startup tab you will see several programs listed with a checkbox beside it. If there is a check mark beside the application listed, the application will startup when your computer starts up.

Regards
ELLIN

Program button no response


The cd shouldn't be making a noise, but your cd drive might be, there could be something wrong with it try to identify any cracks or marks on the cd, if there are any that may be the cause behind the program not responding. The loud hum you're hearing could be due to overheating, carefully check your computers temperature, if the cd is damage the loud hum may be produced due to the cd drive overworking itself trying to read a damaged disc. Hope this helps.

Loud grinding or humming noise


It sounds like you have a fan with a bunch of gunk on it. Get a can of compressed air and clean out all the vents and fans.

Also, take a close look at your video card's fan. It might be the culprit. Many times when they are about to die they make a lot of noise...

My Acer Aspire One AOA150 's fan is very loud and warm


I'd suggest that you carefully pull the base of your Acer apart - taking out the screw, and keeping track of them. See if your fan is dirty - I have an Acer as well, and if it's dirty, it get loud, and HOT!

A quick cleaning does wonders!

It sounds like your compressor has failed. The hum is the compressor trying to start and the click following is the over current protector opening.
