Beaglebone Boot up issue


I have connected an ethernet cable to my beaglebone, but for some reason I am not able to make SSH connection to it. I also tried connecting the LCD display through HDMI port to see what is going wrong at the bootup due to which SSH connection is not working, but on LCD all it shows is the linux logo at the boot up and then the screen remains blank forever.

Is there a way to solve this issue. I have lot of data in this Beaglebone.
