Try to check in the Bios if there's an option to adjust the fan speed of your CPU. If not try speedfan, its a freeware : http://www.almico.com/sfdownload.php

Most desktops have fans fitted, especially in the power supply.
The bearings and not that good and become noisy when older. They are replaceable but a replacement power supply is far less effort.
Show the fans a plastic pipe from a vacyym cleaner from time to time, that will make the fans more efficient and reduce the wear and noise.
The hard drive can get noisy also, (if it is I would before it is too late), recommend replacing it.
Hope that helps.

Acer Veriton M498g - ui3540c won't start


Need more info, Give as much detail as you can. What happens when you push the on/off button? Fan spin? LED's Blink? Any thing on the screen? Sound? Does the computer try to start and a second later shut down? Check the power cord, check the AC outlet? Is it on a UPS? Try AC outlet? Can you get to BIOS or Boot Menu? ETC.

My Acer Veriton X480 turns off after few seconds and won't boot.


Have you cleaned it lately? Is it getting sufficent air flow? A few cans of compressed air and a can of Electronic Contact Cleaner spray. If so, I would suggest the PSU may be bad. Reseat the memory mods, Try to reboot. If it starts, LED's blink, then completely powers off, Test the PSU with a multimeter, replace if necessary. Do you get anything on the monitor? Or does it shut down before? Had you done any hardware or software updates/upgrades?

The acer veriton m460 has three faulty capacitors. Check and see if you have bulgy capacitors. I have ten of these computers and all have three blown capacitors.

Acer Veriton 7800 goes into Hibernation on startup


i know what it is. you updated your ram on your veriton station correct ?
and you thought what i thought , i'll keep my computer open just in case i have to change something.

That's the problem right there. theres a special van in there that needs the computer to be closed in order to work properly. the hibernation is the protection.

If you turn off and close the computer, go to your bios and go to pc health and reset the upper option and you're set to go :D

Power supply fan is makeing a lot of noise


1) Unplug the power cord and give the fan a good cleaning
with a soft paint brush and a vacuum cleaner.

i.e. Let the fans spin up by the vacuum and than bring
the brush against it.

2) If this fails, it's time to replace the fan:

a) Upgrade or replace the power supply enclosure with more
power/higher quality.

This is usually a good investment anyway.

b) Replace the fan only as described below:


Unplug the power cord

Open up the computer (remove sides)

Unplug all the power supply harnesses from
the mother board, drives and chassis fans.

Unscrew and remove the complete power supply
enclosure at back of computer (ie top of the tower)

Vacuum it out as much as possible.

Disassemble the power supply enclosure by removing
more screws and removing the metal cover.

Unplug the fan from the circuit board, remove it
and take it to a computer store/ builder.

buy another fan just like it

reverse the process to put your computer back together.

1) A new power supply should cost $65 to $120
depending on power and quality. The bigger the better.

But make sure it fits mechanically into the existing chassis
and that the AT generation matches ***********-board.

2) A new fan should cost $15 to $25. Makes sure it runs on
the same voltage, and that it is physically compatible.
