Windows 7, PC Shut Down when CPU is HOT!

"This is more likely to be your motherboard, and you don't want to disable it. It's a safety feature.

If your CPU is overheating, you might have airflow issues, so clean any dust out of your laptop's vents, and see if it still happens."

"The best thing is NOT to disable the safety feature, since your laptop won't live for a very long time that way. You can try reattaching the processor after adding new thermal paste, but I don't think this is going to bring it down too much though. The best is to send is back to Acer.

This is pretty common with Acer laptops, since I know a friend as well with the exact same problem, also on an acer laptop.

If it happens while playing games (heavy operation), the best you can do now is switch to playstation 2 or xbox 360, or just use a desktop computer."
