Hello, I have a Dell PP70L and the computer is shutting down about 5-10 seconds after its turned on. Nothing comes up on the screen either. I have taken it apart and cleaned it out.

Thank you.

Hi Chronic1553
Can you at any time hear the CPU fan working?

Yes it is running, I also have noticed that the caps lock indicator light flashes.

Have you tried running with only the battery fitted or the battery removed and only the AC adapter connected?

Yea I have tried that, same thing. The only thing that seems to change anything is if I boot it with out the ram sticks in it, the caps lock indicator does not flash.

Try connecting the laptop to an external screen to see if you at any time you get a display of any kind.
What you describe happening is a common symptom of overheating which can be caused by a bad CPU fan, poor TIM application, dust and a bad power supply.
