Pc just goes on at night?

I was just on the cell phone on the bed at 2:30 am and my PC just turned on, it is right in front of my bed a PC not a laptop

when I looked at it it was shifted a bit so it is normally so straight | and when I looked at him he was lying

I'm a little scared now, I honestly have to say

Recently my background on the pc has been changing to gray

i have a hdd with all programs and once windows on a sdd7 should i reset windows?

Open it and press your graphics card firmly, as well as the cable to the monitor.

Er

I'll do it tomorrow morning, I'm only 15 and parents are asleep haha

Er

I think that may be because of the dp cable wanted to pull it off and it depends on why

oy

The connector is bent (look, the connection on the graphics card could also be), preferably a new cable.

Er

Cable is 1 month old: /

I'm also scared right now… Hopefully no demon / hacker on it 😳

Maybe it was already bent - or did you pull it out often? Do not think so.
You don't look at new ones, or rarely look at them.

Er

I put it in once because I wanted to pull it out because that didn't work, I left it
