system unit My Computer

[Mau_Li]

Hello everyone, i am new here. 

I ran into a bit of a problem when I disassembled my System unit to give it a clean from dust. 

In the process, I removed all connectors and cleaned it. after which i connected all back and decided to boot my PC.

After just connecting the plug into the socket, my system unit turns on and doesn't go off. 

(my system unit usually turns on for about a second and turns off anytime i plug it into the socket which is very normal)

Please any suggestions as to how i can get my system up and running again?

Thank you

This is bit confusing. Your PC is turning on right away and doesn't shutdown at all? What PSU and other system specs?
