New Cooling Fan is Very Loud

SOURCE: compaq presario R3000 Laptop power and fan problems

Your machine is overheating. Try cleaning the vents with a can of compressed air and making sure the heat sync is free of dust. If that doesn't work, you may need to replace the fans.

Causes of Laptop Overheating Physical Causes of Laptop Overheating
For a properly designed laptop, the most common cause of overheating is blocked air vents. When dust blocks the fans and air vents designed to cool your laptop, overheating results. (In some cases, blocked vents and poor design are related, as some designs are excessively prone to becoming clogged with dust).
Software Causes of Laptop Overheating
In other cases, laptops overheat because the software designed to protect the laptop – specifically by controlling the operation of cooling fans – does not work properly. In some cases, this is due to problems in the computer’s BIOS, and can be cured by upgrading to the most recent BIOS. In other cases, upgrading or changing the computer’s operating system can cause this software to not function.
If, for example, you have upgraded from Windows ME to Windows XP, the system software designed to operate the fans may no longer work properly. (What’s worse, the laptop manufacturer may refuse to provide support in this instance, on the grounds that you changed the operating system and so are no longer operating the system as it was designed to operate.) In other cases, replacing Windows with Linux has led to this problem if the proper Linux utilities to control laptop cooling were not installed.
Design Causes of Laptop Overheating
In a distressing number of cases, laptop overheating results from poor design by the notebook manufacturers. Some manufacturers cram desktop CPUs into laptop configurations, and do not adequately provide for releasing the heat that these desktop CPUs create. Others simply have failed to provide ventilation and cooling systems appropriate for today’s CPU and video chips, which hold many more transistors than in the past and so generate more heat.
Several class actions have been filed against laptop manufacturers due to overheating laptops, including Toshiba and Dell. Previous class actions have led to settlements under which compensation was awarded to owners of overheating laptops who ran up repair bills trying to get the problem fixed. More class actions related to overheating laptop and notebook computers are reportedly under consideration.check here for more information http://www.fonerbooks.com/lap_fan.htm

First

try by resetting the memory..

remove the memory module when powered down..and the mains switched off..there shouldn't be any light on the board...use a static band if available..if not touch the metal part of your machine to discharge static off your hand...resit the memory....if there is 2 or 3 try placing 1 at a time and rebooting....

keep me posted

And if this did fix your issue please do not forget to vote!


Cheers!

Overheated laptops turn off by themselves. It usually is because of the dirt in the fan. Try to clean it up.

hi ken. initially the laptop was booting and staying on although while in safe mode,,that rules out the fan issue... i think the reason why its shutting off now is that the restoration didnt complete and so you basically have an incomplete OS installed,, i suggest the problem may not be hardware but software..u could try reinstalling the OS.. you could do this by either using the OS recovery cd that normally comes along with the compaq laptops,if not then you should have made it..i understand some laptops dont accompany these cds but they have an option to create them..hope you made urs.. also i strongly suggest you do not open your laptop as that will void the warranty..if the above fails,take it to an authorised dealer..regards
