Latitude E6420 won't turn on

Hi all,
I have a Latitude E6420 that won't power up. When I press the power button the laptop starts running but nothing loads on the screen, the fan is spinning at full speed for 10 sec. and then the entire laptop shut down. So far I tested the ram, power brick, and the hdd and they work just fine... Maybe is the motherboard? Or the cpu? Any other suggestions guys?
And since my english is sooo good here's a video of the problem I'm having



Thanks!
