Inspiron 3537 gives continuous short beep and looping restart

Few months back my dell inspiron 3537 64-bit 6GB ram with i5 processor has fell down from table. It worked well even though there was a crack on the backside of the screen near right hinge.  But now from past one week it  giving trouble in many ways ! Whenever I try to start it it either starts to give continuous short beeps or goes into looping restart. I can hear the drive sound and see power led glowing but the screen doesnt display anything except for changing from dark black to light black. Hdd led also doesnt blink. Please help me configure the issue and solve it.
