First thing is make sure the Notebook is not Overheating if, the NB is hot turn it off until the unit is back to normal room temperature and the check if the fan of the NB is functioning and make sure your using it on a flat surface and if the NB is overheating or the fan is not working then BIOS update will help resolving the issue

if the issue is not due to overheating or above steps does not help to resolve the issue then Boot the NB to BIOS then check if the NB turn off Automatically in BIOS screen as well then if it does then its a Hardware issue you should contact the manufacturer

Note: while doing the above steps make sure the ac Adapter is connected to the NB

Acer extensa 5420 bios


Clean out the cooling fan/vents, etc. and try again. If the fan isn't turning, it won't boot up.
If that doesn't work, you may need to disconnect the power supply and battery and then hold down the power button for 30-60 seconds. This will discharge stored energy from your laptop. I'm not sure of the specifics, but this happens to mine every 12-18 months or so. Once you've done that, reconnect the charger and battery and try to power up again. It should work now.
If these steps don't fix it, you have serious problems.

Acer extensa will not boot to windows


What is happening when you press the power Button? Do you see any ligths, Any HDD moves? IF DOES.

TURN OFF by pressing and holding your finger on power button.
wait 60 sec. turn on and repeatedly press several times at F8 button.
If page opens on black and white, Use SAFE MODE.
wait til all line down. Then you will see windows opening in safe mode.
WHat ever you install last, remove, scan your computer for virus,spyware. when its finished, check your computer if need defragmentation. by Accessories>System Tools> Defragment.
If message comes such as windows will do this at schedule time or so.
Just turn off your computer using shotdown option (NOT BROWN BUTTON ON START) go to next arrow.
then turn on again see if windows comes back.
Goodluck
