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

you can try to hover around the fan outlet the dust gathers and stops the cpu cooling down and then the cpu wiil shut down to protect the laptop from overheating if it runs longer but shuts down you will need to get in to the laptop and do the same around the heatsink fan and cpu
Your Toshiba could be overheating.
When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.
Turn the computer off.
Disconnect the AC power.
Remove the battery.
Purchase a can of compressed-air, and give your computer a "blow-job", to remove the dust, because the dust is acting as a layer of insulation, trapping heat inside your computer.
Reload the battery.
Connect the AC power.
Start your laptop, and check that the fans inside the notebook computer are pushing air out of the exhaust-vents. If not, the fan(s) have failed, and you need a professional computer technician to disassemble your computer, and fix the fans.
Could be as simple as a overheating issue. If the computer starts to slow down after running for a few minutes the the CPU could be overheating. You will need to verify that the fan is operating. Also make sure that the underside of the laptop is clear. Make sure not to block any of the air intakes under the computer. And make sure that the side exit for the heat to go out is not blocked from lint ect. You can try using a can of compressed air to blow out the dust in the cpu and heatsink area and see if this helps. If your laptop is only 3 months old then I would not attempt anything further than that because you may void the warranty. Remember that viruses and some programs can cause the computer to slowdown. Make sure you have a good virus scanner on the computer. You should download malwarebytes free version from here http://www.malwarebytes.org/ and run a complete scan. Worst case senario if you have a virus you can use your installation discs that came with your laptop to format the drive and re-install the OS to the factory condition. Make sure to back up your important stuff before you do this. If it still slows down after the re-install then I would think that the CPU fan may have stopped working causing an overheating issue. If that is the case repairs should be covered under the factory warranty.
The keyboard and the bottom of your laptop are very hot when the laptop is working.
The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
Solution: If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
Clean the fan and the heatsink with compressed air.
I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.
The first thing I would check is that the cpu fan is working. You should be able to see the fan come on from the bottom of the laptop. Sometimes the fans can stick from dust and dirt. Then the cpu will get very hot and cause the computer to slow way down. Try using a can of compressed air on the fan and see if it starts working. If the fan is working ok then you might have some type of virus or corrupted installation causing the computer to slow way down. You could try pressing F8 right before windows starts to load. This will bring up a boot menu. Then try booting the computer in safe mode with networking and see if it boots up fairly quickly. Once it boots up in safe mode run your virus scanning software to see if there are any viruses on your computer.
It is overheating. This is the #1 killer for cpu's. First check all your vents to make sure they are dust free and blowing air out. If they are then you'll want to either upgrade your cpu fan or you could buy one of those laptap cooling pads to keep the laptop on while in use. Hope this helps.
The fan may not stay on all the time - its a feature of laptops to help save power. The fan is also variable speed. As the CPU gets hotter, the fan speeds up. When the CPU isn't being used as much and is cooler, the fan slows or even stops. It turns on to full speed when you first turn the laptop on as part of the BIOS system check.
The noise is another issue. You could have a broken "fin" or fan blade. The bearing could be going out. Something may have simply "crawled" inside the fan's output vent. In any case it may be worth your time to have a professional open up the laptop and look at the fan. I have heard a LOT of noisy laptop fans in my day, and believe me it's not the worst thing to put up with.
Overheating. Try using canned air and blowing out vents. If you are comfortable with it, take the laptop apart and clean it out. If not, contact a local computer shop that can do it for you. If cleaning doesn't do it, the CPU heatsink will need reseated or the CPU will need replaced.
That can be normal. Normally cpu fans start up only when cpu reach a determined temperature. After it cools down it stops until temperature reaches starting point again. Generally, when the fan is not working properly, the computer turns itself off after a while because of overheating. If you have this problem, laptop turning itself off because of overheating (check it is not hibernating etc.), then you usually solve it by replacing the laptop cooling fan. Generally, 'fan on laptop intermittent' is not a symptom of malfunction.
