[SOLVED] PC in endless rebot

[NoobKid]

So i was visiting my friend to check if I could upgrade his PC with an SSD. However, my friend tried handing over the PC and lost it by mistake on a ground level (ca. 30cm). We tested and the PC is just going in an endless reboot with no video signal.
All fans are spinning.

PSU, and GPU tested and works fine.

This video shows how the PC behaves: https://drive.google.com/file/d/13XA2z-8uX7K2MnjcqU5FDoi8991esS8y/view

Specs:
CPU: i5
Motherboard: B75
RAM: 8GB DDR3
PSU: Cooler Master 500W
Case: A corsair miditower
GPU: GTX 960
HDD: 1TB

Any idea of what may be broken?

Have yo u tried clearing the CMOS? That would reset the BIOS back to factory settings.
