I don´t know if it´s problem of overheating or processor ... I´m kind of getting tired of this laptop, really. At first, like a month ago, it just stared to shut down at random. I realized, that it´s probably due to overheat and gave it a different possition( different mat), so it can cool of much more effectively and got my self speed fan -so I know the temperature. It worked well, up till yesterday - it started doing it again. This time I noticed, that just before it goes down, processor is overloaded and temperature is just normal.I have no idea what´s the problem, I have new instalation and I never install any nonsence. Also, I keep my register clean. Can anyone give me some advice as how to solve this, please?
and -very sorry about my english - I´m a foreigner.
I have the same model and had the same problem. My simple fix was to take off the back panel and remove the fan assembly (2 small screws). Once I had the fan off I saw what looked like a "filter" between the fan output and the metal heat exchanger at the back vent. turns out the "filter" was actually a hair/dust/dirt ball in the exact shape of the fan output. Pulled it out, blew out the rest of the dust with a can of air, and re-assembled. Now the airflow is back to normal and no more overheating issues. Try it before you spend $ on something that may not be the fix. Good Luck,

The laptop must be dismantled to access the motherboard, buy a can of compressed air attach straw. Now remove fan and the heatsink, blow out all open ports and fins on the heatsink and fan, next! remove thermal grease from the processor and heatsink with rubbing alcohol and a paper towel, now! apply fresh thermal grease to the processor and heatsink, "small thin layer evenly spread" now assemble, "solves most heat related issues"
The processor has to perform large amount of work while surfing , especially while usingvideos and animationMultiple windows/tabsnumber of browserwhich in turn produces lot of heat . The heat produced is managed by the interneal heat sink and inbuilt cooling fans.But this cooling process may get affected by the blockage in air vents due to dust.So to safeguard the laptop form overheat, it automatically shuts down. One simple try :Go to the Adobe flash properties and disable Hardware acceleration for online content. That ought to stop the system from rebooting or crashing.
Else...Its better to call a technician when it shuts down often.....
If the games that cause your computer to shut down feature high resolution graphics or fast 3D rendering, then the problem could be insufficient processor cooling. Once the processor gets overheated, it goes into thermal shut down.
If, while you play, the computer runs hot before it shuts down (check the cooling fan outlet), then these are some of the possible reasons:
-cooling fan blades could be obstructed by dust - cooling fan needs to be cleaned or replaced
-heatsink radiator and / or air outlet could be obstructed by dust - also need(s) to be cleaned
-thermally conductive grease on the microprocessor heatsink could be partially or entirely dried up - old grease needs to be carefully removed and new grease applied (caution - do not use any kind of thermal grease that contains metallic particles like silver or aluminium - you might short out the processor - only use the kinds which are electrically nonconductive)
of course the problem could be elsewhere, but the above mentioned problems turn out to be a common issue with many laptop computers after a few years use, regardless of manufacturer brand and model, also it could be any of or the combination of any or all of the above problems (obstructed air outlet leads to more dust being deposited on the fan blades, more dust on the fan and outlet leads to processor overheating which leads to thermal grease drying which leads to even more overheating and so on...)
I have heard of this problem many times and it is usually due to overheating and motherboard problem. But first thing that you need to check is if the fan is working properly or not. You can use a canned air to blow out dust and accumulated particles from the fan.
However, freezing may also be caused by faulty processor. The unit may freeze (and overheat) while booting up, while using the computer or before the operating system loads if the processor is failing. To verify if the processor is failing, just access the BIOS (Basic Input/Output System) setup and test if it will overheat from there. If it does, surely the processor and/or motherboard needs to be replaced.
Your laptop could be shutting down for a number of reasons. The most likely is overheating or corrupt files/drivers. Check the fan is running and free from dust and fluff etc. Run CHKDSK/F from the start prompt, that should sort out any bad files/sectors. Hope that helps.
VISTA HAS PROBLEMS WITH CERTAIN GRAPHICS CARDS AND WITH JAVA-SCRIPT -APPLETTS, CHECK AND SEE HOW MUCH MEMORY YOUR COMPUTER CAME WITH, I HAD A CUSTOMER WITH THE SAME PROBLEM AND VISTA DEMANDS A LOT OF WHAT IS CALLED SYSTEM-MEMORY FOR SIMPLE THINGS THAT THE COMPUTER DOES. AFTER UPGRADING THE MEMORY AND THE HARD DRIVE IT STILL PERSISTED SO EVENTUALLY SHE BACK-GRADED TO XP WITH SERVICE PACK 2, BUT IF YOU WANT TO KEEP VISTA GO TO MICROSOFT UPDATES AND SEE IF THEY HAVE A UTILITIES SUITE THAT CAN HELP WITH THIS PROBLEM. KEEP ME POSTED JON T
