PC turns restarting every 5 seconds. Help pls.

I unplugged my pc to clean the dust out. I just did superficial cleaning off the case and from inside of the case. I didnt touch any fans or components. After i closed my pc and tried to turn it on it started up and then every 5 seconds it restarts. I did a small video showing the issue.
