UnExpected Shutdown, non overhating problem

It seems like that your pc is old when you work on it procesdor heats and fans cools but in your case it is overheating your lapy need service open laptop and clear the dust near fan if you are a expert then apply cooling paste on processor head or change the heat sink

Try to disassamble your laptop and clean the dust from it, and make sure the processor fan is working.

Computer have a mechanism to protect the processor from overheating that can damage them, soo it will shutdown automatically.

If the Computer restarts randomly, then the issue might be due to any damaged Operating System Files.
But, if the Computer shuts down randomly, it is due to the Processor.
All the Processors will be designed in such a way that, if there is any overheating issues, the Computer will shut down randomly.
The overheating might occur due to the malfunction of the Cooling Fan in the Computer.
As this is a overheating issue, it would be better to get the Unit examined at the Service Center.
Replacing the Cooling Fan in the Computer should resolve the issue.

Hello my friend,usually laptops when are overheating because of the processor or graphic card they start restarting or shutting down.Was your laptop warm when shut down or you was watching video or playing a game?

This sounds like a overheating problem (a CPU thermal shutdown).
This is caused by a faulty fan or the heat-sink and fan is clogged with dust. Check the fan to see if it spins freely, if not replace the faulty fan. Check the fan/heatsink assembly and remove/vacuum the dust from these components.

This sounds like an overheating issue. Make sure your vents are free of dust and debri by using a can of compressed air. Then try powering on listening to see if your fan is spinning. If it is not you'll need to replace it. If it is then make sure you are using the laptop on a cool hard surface rather than cloth or such. If you still have the problem then the most inexpensive fix would be to purchase a laptop colling pad to use underneath, usually $20-40 at most computer stores. Hope this helps.

Depending on the age of the laptop, it could well be overheating. Let it cool down good, and try again. If that is the problem, you will have to clean out the cooling system with a can of air.

DO NOT USE AN AIR COMPRESSOR ! ! !

How did you clean your fan? How much stuff was in there?

The problem you're experiencing sure sounds like a thermal shutdown. Try using compressed air on both the fan's intake and outtake.

Do you know for sure the fan runs?

If that doesn't solve it, you may have to pop the case and see if you've got a physical break in teh cooling system between the fan and the CPU.

If your laptop is Vista, this page should have a download for a Vista touchpad driver:

If it's an XP laptop, try this link:

If one of them works, let me know which one and rate appropriately. If neither of them do, we'll try something else.

Thanks.
