Shutdown quickly

[goodaccent]

I have Toshiba satellite C660-162 laptop. I cleaned every thing inside the laptop. When I turn it on sometimes it boots and sometimes it doesn't. When it doesn't I can hear the sound of the fan and I can feel the hot air, after few seconds the sound of the fan became louder then the device shutdown. When it boots, after few seconds watching the desk top of windows, suddenly the computer shutdown.
Please help me.

The computer is either overheating or there is a short circuit. Best thing is to consult with http://forums.toshiba.com/ and ask other owners if they had that problem ever.

Question I have is what make/model it is and did you remove any heatsinks etc, and if you removed heatsinks or heatpads if you applied new thermal compound?

Obviously, sudden shutdowns are caused by overheating of your computer because you feel hot air. Hence, try checking the airflow in your unit. Make sure the fan is spinning and the environment is cool.
