laptop continuous beep sound on startup

Hi Geek's

I am using dell Inspiron N5010. I am using this laptop for more than 5 years. The laptop worked flawlessly. last week i have changed my Operating system to Windows 10 and installed some drivers. Suddenly my laptop got restarted and keep on  producing beep sound. So manually i turned off my laptop. After a hour switched on my laptop the same beep sound is produced and display is not getting on. In my laptop except center indicator light both the lights have been turned on. Kindly provide a smart solution to get rid of this problem.

Regards,
