Ok, after trawling Acers unbelievably slow website, I was able to find no useful information at all except that it appears your laptop has 3 ventilation areas - one on the side, one on the back & one underneath where the fan is.
The easiest was to clean these is be using a can of compressed air to clear out any dust etc that may lurking in there. Just blow the air through each of the vents. Also check that the fan on underside is working ok. NB This may only come on after the laptop reaches a certain temperature so don't panic if it doesn't come on right away or if it doesn't stay on the whole time.
I assume there's no temperature monitoring utility on your laptop, right? If there isn't, then try hmonitor:http://www.majorgeek...nitor_d269.html
If one of these is able to monitor the cpu temperature, then I suggest you use it to keep an eye on the temps for a while, especially whilst running a game etc. Let me know what sort of temperatures you are getting.
RE. your previous questions:
Obviously overheating can cause permanent damage, especially to the cpu. However, the reason the system shuts down automatically is to try & prevent damage. That said, repeated overheating, even when the system shuts down to prevent damage, still won't do it much good!
Apart from cleaning out the vents, also make sure you always place the laptop on a flat surface (i.e not directly on your lap, or on the bed/cushion etc). This is important
, especially with laptops that have the fan+vent on the underside (like yours does).
If all else fails, then you can buy an external laptop cooler, such as the one in the link below:http://www.amazon.co...r/dp/B0000BVYTV
