Hello,
I have an Acer Aspire 5349. It acts like the cpu is overheating and shuts down. Reseated heatsink, and cleaned fan. Same results. Bought new fan and heatsink. Initially ran for three hours, then when I installed updates, it shut down. Monitored CPU heat and usage with "CoreTemp", no significant heat up even with multiple tasks running. I'm at a loss. Pretty sure that its a heat issue because when it first started to appear I stuck the whole laptop in the fridge and it ran for hours.

I am having the exact same problem. The computer was perfect, but suddenly it became like that - shutting down. I tried to clean, to coll, to install windows 8 again, to change the HD. Nothing helps.

My Acer 5742 keeps shutting down on start up, doesn't even get on to the windows screen. keeps turning itself on and off through the same cycles for hours. Closed the lid popped it in the fridge and on the 2 occasions I have done this it has booted up ok within 5-10 mins. So this has to be a temperature related issue!!

it is possibly that it cant get enough cool air as when my acer aspire 5733 blacks out it had been on duvets and blankets it occasionaly does it on my lap but i find it does it less often if it is slightly raised. like i lay down and bend my knees and pun the laptop on my lap and on my stomach so it can breath.
