[SOLVED] Newly built pc boots then shuts off soon after

[Jaarnold]

I just finished building a new pc for the 100th time but for some reason it won’t boot. I connect the 2 pins with a screwdriver to start it and it comes on for a split second and goes right off ?
I’ve tried:
switching ram slot/ new ram
Different gpu
Building on a cardboard box
Detaching 4 pin from 24 pin
Unplug all the case fans

Help

(Components:
Pentium g4500
Stock cpu cooler
Rx 480 4GB
MSI H310M pro-VLH PLUS
Thermaltake smart 500w PSU
Vengeance LPX 3600mhz 16gb)

I do not see that CPU on the CPU supported list for that board. It's not working because of that
