laptop makes a click noise after 15 sec shuts down after 3 times

I have a toshiba L505D-S5965 I replaced the DC jack. now computer will only come on for 15 sec then there a click ( not a beep) and then comes back on right away then about 15 sec make the click sound
after the third time doing this it turns off for good.
it sounds like it is coming from the hard drive area. I took off the top turned on computer and listen sounds like from the hard drive. No lights come on the computer.Screen stays black. I took out the hard drive same thing.
I only took off the keyboard and the top of computer put the new DC jack. This DC jack you just plug into the MB. I did blow the fan off of dust. Could I have did something spinning it to fast with the air?
Any help out there.
Thanks
