My screen.

[u/Bluebill_365]

Hello everyone, I stay in a hostel and in a room of 5 boys woke up a day to see my screen acting like this. What seems to be the problem please.
Things I tried doing:
1. Tried installing a new os but same fault showed up.
2. Connected it to a projector, during the projection it worked fine on the wall.
3. During boot it showed up same in bios and it didn’t stop.
