My PC has been having booting trouble for a couple days but today it got worse. It turns on by itself and then trips out and switches back off, I took a video (if I can reply to this with the video I will). My guess is power supply fault but I’m not very good with tech stuff so any help would be amazing thankyou.

Also forgot to mention, the socket I plugged it into now doesn’t work at all with anything plugged into it and I tried another socket and that one has broke too :/
