|Quite often with laptops I have found freezing problems can occur because of overheating. You have pointed out that this often happens when you run certain programs. Because some software can be labour intensive the fan speeds up to cool the internal components, if these fail to cool adequately this can cause the laptop to freeze and in some cases shutdown completely. |
Do you find that when the laptop freezes and you force it to restart that it freezes up again even sooner when you try to run the same jobs?
I have linked a YouTube clip showing someone cleaning their cooling system. You can see in the clip how much dust has accumulated and compacted in their laptops airflow channels. The really important information is shown in the first 6 minutes. Please, if you watch further and decide you would like to attempt to see if this is the problem and solve it DON'T USE A VACUUM CLEANER to extract the dust as the rushing air from a vacuum cleaner can create static electricity and there is some very sensitive components which can be damaged. Always exercise anti-static precautions. I use tweezers as shown in the clip followed by a sticky gel designed for exactly this kind of task called cyberclean. It really does a wonderful job at pulling any left over debris free. You can also use canned compressed air to blow the excess junk free. These are available at most computer shops.
There are knowledgable people here at computing.net that can probably tell you of a way to identify an overheating problem without opening the laptop up. For myself I have found it easier to visually have a look and determine how much dust has accumulated around the fan. Cleaning it is the time consuming part. Also take a note of which screws go where as you may find there are longer screws and shorter screws which need to go back to where they came from.
