There is probably a dust buildup on the heatsync. The heatsync is located right underneath the fan. underneath the heatsync is the proccessor. if the heatsync cannot properly distribute the heat that the prosessor is creating than the computer will overheat.
The solution to this is to get a can of compressed air, unplug the computer and open it. In between every fin blow the air. put it back together and start her up should be just fine.

My acer Keeps shutting down Could it just be dirty or do need to upgrade the power supply


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with 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 sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

My computer keeps shutting down automatically.


If it is shutting down by itself to a full power off then the first thing you should check is heat. Software could be an issue but the safe bet would be hardware. It sounds like it's overheating and shutting down to prevent damage. Check to see if the computer itself is warmer than usual. Listen carefully for sounds that are different or missing. It could be that a fan that failed that is causing an excess build up of heat. If you are comfortable doing so you should remove the cover and used a can of compressed air to blow dust off the boards and fans or if your careful you can use a vacuum, emphasis on careful.

Possible overheating problem for Acer Aspire mini L100


I am not totally sure if this is the problem, but I would suggest that you may have a power supply issue or possibly it going out. If the computer runs fine, and then shuts down, than this can be more symptomatic to a overheating issue.

In my limited experience with overheat issues, the computer actually smelled like it was getting hot, and then it would slow down and then sometimes stop. Most computers have fail safe settings where they either alarm, or shut down or both when they overheat.

Hi i have a acer aspire 5044 and it keeps shutting it self down after 10 - 15 mins of use


This sounds like an overheating issue. You need to open the case and check for dust and clean it out. If dust is not the issue then the heatsink compound will need to be changed, this will involve removing the proccessor heatsink and fan, removing the old compound and applying new.
If you are familiar with the BIOS you can check your processor heat readings just prior to the shut down if you can.

Computer keeps shutting off


the fans must work for the processor not to overheat..

thats why it crashes.. processors or certain hardwares need a certain temperature for it to run.

try repairing the fan it will help. and also clean dust on your board it insulates and increases heat inside causing your pc not to last long
