Laptop won't power on

[dmal]

i have a compaq presario c350ea laptop. it powers on and sounds as if its booting for a few seconds then the led on the power butto just starts flashing and it doesnt display anything. I have checked ram, took out battert and also took out the dvd drive and its still the same. Is my mainboard faulty or am i missing something

Pull out the hard drive and see if you get any start up info on the screen
