PC not quiet running anymore!

My computer has always been very quiet running. All of a sudden it sounds like a plane getting ready to take off. The fan in the front is super loud. The inside is clean and free of all dust. What has caused this? Is it getting ready to crash? Maybe need a new fan motor? The PC still works great like it always has. Have to crank up the tv to be heard over the small fan noise.

SOURCE: Fan/Overheating issues averatec 3200 series Laptop

I had the same problem and went into the CMOS, Power Management and ran the FAN Learning feature. It runs for about 10 minutes and then chooses the right fan speed for your machine. My machine's fan was running really high. After this test, it ran a lot slower and did not overheat anymore. I also use a fan underneath the machine that plugs into a USB port for extra air control. No more issues.

SOURCE: Loud Noise on laptop when booting

Most likely it is the POST throttling up the fan to 100% during boot up. Then it switches over to ACPI(?) power manangement and Windows manages your fan speed to extend battery life.

Go to Dell Support Site
Download the latest BIOS updates and run it.

If it continues, try a can of compressed air, and breifly blow out any debris from the system fan. Bits of paper and critter-fur can get sucked up into the system.

SOURCE: Rattling Fan Noise

Unfortunately, even though the laptop is only 4 mths. old, sounds like the bearings in the fan are going out. I would have it replaced. If the fan fails, your processor will overheat and that could be problematic.

SOURCE: Annoying noise from inside my Vaio

I had the same problem with my Vaio, and I called in Sony Support and they called in a technician who came to my house in 2 days! Apparantly Sony got a batch of defective fans and if you are still under warranty they will replace it for free. Good luck!

SOURCE: HP Pavilion DV6500 - The fan makes too much noise!

HP deliberately design their laptops to breakdown just after the warranty ... my HP-authorized repair shop told me that there is no way to clean everywhere inside the unit, without complex, nearly complete dismantling.

But I bought another Pavilion!  But I learnt by smashing apart my first Pavvy.  There is only one cooling fan.  

Remove the battery.  Put a narrow plastic stick thru the intake slot, to stop the fan spinning.  Then use a hair dryer, without heat, to push air into every air hole you can find.  Repeat with a low-power vacuum cleaner.  

After 4 years, sell it, smash it or get rid of it.

My audio did not work anymore

If the audio was working earlier and than all of a sudden quit working I suggest making sure that it is plugged into the correct port, than restart the computer and try to play a song than. If it still doesn't work, sounds like your on-board audio card is finished. ALSO make sure your volumes aren't muted.

Something in my tower sounds like a plane getting ready to take off. What is it?

There's probably something touching the cpu or case fan. I'd take it outside and clean the tower out with two cans of compressed air. Once you've got it clean out visually inspect the fans to make sure they are clear of all obstructions.

I have a Dell T3400 deskto pc running win xp. When

Check your BIOS settings to see if "smart fan" settings are enabled or disabled.

If they are disabled, your fan will run at max speed all the time.

Once enabled, the fan should only speed up as your cpu heats up, and then turn itself down once a lower temperature is reached.

Zt desktop rear fan is very noisy upon startup. usually will quiet down after a while or with a smack. Have already cleaned all fans. Sound appears to come from the fan in the very back.

depends on how much use the fan has had in its life, ive got a new pc and the 120mm fan supplied in the rear is not the top of the range and is already making a noise after only a few months of service life. just bite the bullet and buy a new one, you get what you pay for in terms of fans..go for a ball-raced one, not a sintered bronze oiled for life bearing,the fan impellers only need to be slightly out of balance at high speed and they will wear the bearings very fast indeed. i run rc electric planes powered by very fast fans ( 15000-35000 rpm ) and it realy shows on them...good luck & buy a new one :)

Does not boot, after turned off suddenly

check to see that it is not overheating. If cpu fan is not blowing (could be frozen up) or if the fan in the power supply is clogged with dust, the computer may be overheating and refusing to some on. If it is dust, arrange to blow it out completely. take off cover and try to start the machine, the fan should turn on the CPU.

Pc does not always boot up

A solid or blinking Amber power button indicates a voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.
