Inspiron 17R 5737 suddenly went off, Now wont turn now

Question

I recently updated my OS to window 10 and as recommended by dell, updated all drivers and the bios. After updating the bios and the system restated, it worked for about ten minutes and then suddenly went off. Now it wont turn on. When i press the power button nothing shows but the power indicator at the front shows for few seconds then later blinks, stays few seconds, goes off again,. Does this continuosly. I have changed charger, pressed and held power with the down for 2minutes without the battery and nothing is happening. Have removed the ram cleaned the pc and other things yet nothing happens. Please help me as i am out of ideas

Try connecting the system to an external display and see if you get any display. Does go you get a lcd backlight when you power the system on. Do send me a private message with the service tag and the registered owner's name and email address.
