PC turns on weirdly then doesn't boot

[Prop]

My PC was working fine a second ago, but I unplugged it and set it up in a different room and now it’s not working. When I press the power button, it turns on (lights up and fan starts), turns off after a few seconds, then turns on again and stays on but the whole time it doesn’t boot. I’ve removed my graphics card and it hasn’t changed anything, but when I was plugged in the fan would spin but it didn’t light up. I don’t know what to do. (Video attatched)

Side note, as I’m not sure if it’s relevant. The power button will turn it on but when I try to turn it off, it doesn’t work. Only a manual disconnect turns it off

You have post on a tech assistance forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Please provide information about your computer, is it a custom build or brand name such as Dell or HP, if a brand name, provide the model name or series number (not serial) if a custom build post the brand and model name or number for the CPU, MB, the RAM (including the amount) add on video card if one is used and the PSU (power supply unit) providing these details will enable folk to better assist you.
