OverheatingWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the 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 with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

the cpu could be over heating make sure its secure if you like get some thermal paste from your local pc world put a little on the top of the cpu under the cpu fan and replace fan securely might work be carefull....bonnell

There are a couple of things that can go wrong with it. The most common thing on laptops is overheating.

You will know if your laptop is overheating if it happens one ore more of the following:
-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.).
Follow this steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave the laptop in a closed car on a sunny day
-Don't place the laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible, not on your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner

If it is not overheating, then it is a hardware failure. Could be the RAM memory, processor or the motherboard. You can test the RAM with this program: http://hcidesign.com/memtest/MemTest.zip

If RAM is ok, then only replacing hardware equipment could corner the problem.

I think that the CPU fan isn't working as it should and the CPU is overheating quickly. If the CPU is heating too fast, the mainboard is automaticly shutting down the all PC to prevent damage. Your thermal paste might be gone. Isn't the computer giving any sounds or LED flashes ?

You might need to re-apply some thermal grease onto the CPU's & chipset's surface beneath the heat sink. You might also need to clean the heat sink's vents.

Posible over heating issue, (issue with the fan, processor or heatsink)
>Overheating triggers auto-shutdown to protect the CPU
>Memory module going bad;
>Power supply going bad.

Computer usually shuts down if it is over heating so it won't melt down. There is a command on how to disable the auto shut down but it may affect your computer badly.

I would suggest to reformat your computer first before dealing with the hardware issue to avoid part replacement.

Listen for fans coming on, as this sounds like overheating issue. If fans kick in and then stay constant or dont work at all.
The link is for Notebook hardware control, this will monitor the temp among other things (only reference as a guide any software can give you an indication but not exact temp) Generally if a laptop hits 90c it will auto cutout to stop major hardware failure normal running temp (40-55c upwards depending on use) http://www.pbus-167.com/
If the machine is overheating it could be due to blocked vents, faulty heatsink, fans not working or incorrect fitting and thermal paste.
In all honesty if this is due to overheat problems, as the machine has been cutting out my strong advice would be to do all the above ESPECIALLY re-apply thermal paste (arctic silver5) to cpu, it takes about 100-200 hours of use to start to work 100%.
hope this helps, let me know if i can be of further help

When you encounter about this issue this is overheating problem maybe the CPU fan is not spinning and faulty already, you need to check the CPU fan and replace a new one.

Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed.

Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot.

The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down.

Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

if for any reason the computer shuts off immediately it could be from the CPU fan, your computer probably has problem in its coling system, it could be the fan has so many dust obstruction, to solve this you need an expert to open up your laptop and clean the fan. in theory if the cpu reaches its peak temp. it will automatically shuts down to prevent damaged to your system. hope this helps you...

check the cpu fan it is not working properly need clean sometime full of dast that why always became heat. epected of overheating is automatically shut down...

repair you cpu fan disasimble you laptop then check the cpu fan

thanks
