Screen becomes black with white lines

[M-ASAD-Z]

So I am using my laptop and its working perfectly. Then I just move it a little and the screen goes black with white lines or somewhat colour full.. Image attached... Sometime it says windows ran into a problem... But when I just restart all these problems go away it boots up fine like their was no issue at all... I think it happens cuz of pressure to its bottom cover but what should I do I just bought it for my university
