CPU at 90°C? you are going to fry.. it could be three why it will overheat

1)When the laptop os operated on Bed that closes all the air ventilation that makes the laptop to overheat(operate the laptop on flat surface)

2)May be Dust on the heat sink as well as the fans..it is better to re-install the heat sink and re-apply thermal compound.. and clean the fans(if you don't how to do this give it to service center)

3)poor hardware quality.. in this situation you need to get addition laptop cooler Pads http://www.amazon.com/Cooler-Master-NotePal-Ultra-...

Heat

The Acer Aspire Ethos 8951G stayed pleasantly cool throughout our testing. After we played video at full screen for 15 minutes, the touchpad measured a cool 87 degrees, the keyboard a reasonable 89 degrees, and the bottom a chilly 84 degrees Fahrenheit. We consider temperatures below 90 degrees extremely comfortable. Have a read at the link.

Go to Target/Wal-Mart, cheapest laptop coolers you'll ever find. You can return it in like 30 days I think, giving you time to buy a new laptop. :)

EDIT: Dont dare listen to the other guy by putting it in the freezer or fridge, youll say goodbye to your computer forever and all of the personal things you have in there.

SHUT IT OFF NOW AND PUT IN THE FREEZER THAT THING IS GONNA FRY OR CATCH FIRE.
