Laptop acts like CPU is overheating - after ~ 15 mins. computer slows to crawl, both fans start and never stop running.
My laptop, which has been working
great for the past 6 years, had 1 GB free on a 20 GB hard drive. To free space
I removed several programs including Norton SystemWorks. I also added a USB
Linksys Wireless device and driver to connect my recently subscribed DSL
connection. It was around this time that I noticed that after about 15 minutes
of running the two fans at the rear of the laptop would come on and never shut
off. Also, the computer would start to slow down to the point of making any
browsing impossible. I purchased “The Ultimate
Troubleshooter” to see what I could find. Besides some minor program issues and
suggestions, which when corrected did nothing for the slow down issue, I did
notice the “Load Unload Cycle Count” was not “OK”. My understanding is that
this is a hard drive problem and should not cause an overheating processor-like
symptom. I also took the keyboard off to see if the inside of the computer was
dirty, but everything was clean (I monthly use canned air to clean the grill).
I did notice that, when taking the heat plate off from the processor, there was
no adhesive. This did not seem to be a problem for six years, so I doubt this
is the cause of the slow down (I did make sure no oils from my hands touched
the processor or plate). The processor does slow down, so it
should be able to cool. The Pentium III does not have a heat sensor, so I don’t
know the temperatures involved. It does not appear to be enough to shut down
the computer. Is the processor going bad? Does
the plate and processor need thermo adhesive? Could the Load Unload Cycle Count
be the cause of the slow down? Did I remove something critical when I
uninstalled the programs? Do I have a bad driver (all appear to be up to date)? I would appreciate any help or
advise you can provide. Thank you, Francis Scott Zimmer firstname.lastname@example.org

I agree with Joe Boss. with only 1G of free space, you don't have much room for a swap file. Removing your keyboard and using compressed air can be good and bad. Some heat sink/cooling fan assemblies need to cleaned out from the outside in (to remove dust and etc from the inside of the cooling fins) otherwise the cpu could get hot and slow down.

Sounds like the hdd is just loaded if all you have freei s 1 gb and that makes the cpu move slower no if 6 yrs aith out goop is fine not that.
1. I suggest backing up only important personal data and formating & reloading the original (prefered oem xp for example) or any upgraded os you have access to eith software or some computers have a recovery process on the hard drive ( hit f X to start recovery process) this will clean all the junk off & give you back your original speed only install what programs / data needed use a good antivirus such as avast and antispyware such as defender from windows

This is likely due to overheating. Use some canned air and blow out the cooling fans and heat sinks on the bottom and back of the computer. In worse case scenario you will need to take it to a repair shop and have them open the case and clean out the blockage and perhaps re-grease the CPU heatsink.
An alternative is to get a can of compressed air used to clean computers. Put the nozzle on and spray it in every hole you can see without putting the nozzle itself inside the laptop.
Do this outside with glasses on.
You may also want to remove the hard drive and ROM drive.
Take a peek here for more ideas of what is involved.
There are a few are tips for various things in there.
DON'T touch the CPU cooler unless you know what you are doing and have some thermal grease for CPUs to hand.
To make newer laptops last longer between cleaning a good 3 fan cooling pad is suggested. never use a laptop on soft surfaces as the ventilation can act as a mini vacuum cleaner and encourage dirt build up. Soft surfaces also block the vents causing fans to run more and burn out sooner.
Also somebody else here had the same type of question: http://answers.yahoo.com/question/index?qid=20090207210838AA922iE
From my experience as long as its not running over 100 then you'll be fine. If you have any doubts about your computer overheating you can always apply more compound to the heatsink and also buy a bigger one where the fan runs faster to keep things cooler inside of the case and always remember to have the side doors on as well.
When the laptop freezes up on you does the keyboard or anywhere on the top cover feel very hot if so check to see if the fan is even blowing, if it is blowing then its possible there is dirt on the heatsink fan that is blocking the air flow and thats causing the overheating. You would need to take apart the laptop to get to the cpu heatsink to remove all the dirt.
if the fan isn't running at all then you would need to get a new fan.
If the fan is running and there is no dirt or debris near the heatsink then that means the motherboard is not reglulating the voltage properly and the motherboard needs to get replaced.
if nothing is feeling very warm or hot to the touch and the system is locking up then the hard drive may have bad sectors and the hard drive would need to be replaced.
uninstall unnecessary program,scan your PC for possible malware with your updated anti virus,expired antivirus can slow your pc to half of it's speed.Manage your start up program only run program that you nid when you open your PC.Last thing is defrag your PC.
This is normal behavior. Fans normally only run when they are needed, and your computer has multiple temperature sensors that direct this behavior (they are primarily located on the CPU, which could explain why the fans all worked when you took the CPU out). You should only be concerned about the fans stopping if your computer is, indeed, overheating.
Hi have you cleaned the heatsink?
Also replace the paste on the CPU, also you could try installing an extra fan on the case to increase air flow.
Also check that your RAM is seated properly and any other chip and card on your board is firmly plugged in.
If all this fails replace your CPU.
