Computer won’t turn on. Suspected CPU

Feb 10, 2019
So I recently decided to put together a new PC and here are the specs:

CPU: i5-7600k
Motherboard: MSI B360 Gaming Plus
Graphics Card: 1050 Ti 4G (4GB)
RAM: 8 GB (2 X 4GB Viper DDR4 @ 2400 MHz)
PSU: Antec VP - 450 (450 Watt)
Case: Deepcool Genome ROG Edition

The system will flicker on for a second when I turn the power on (all fans on + RGBs flash) and the motherboard LED DeBug lights all are off except the CPU light flashes. I tried all of the steps in the troubleshoot guide and found that if I unplug the CPU power the system will stay on, however, of course no display and LED DeBug stays on. I did end up with some thermal paste on the wrong side of the CPU (no, I did not do it purposefully, very small amount from my hand from cleaning it off originally). This CPU came from my old system which was running perfectly fine. I’m not sure what to do to get the system running again.

Edit: When I built my first computer the motherboard did not have the proper BIOS update so it had to be sent for an update before it could run. During that time the system would cut on and stay on but no display. So the current issue would be a power supply issue? (The old motherboard uses 4-pin for CPU and this one uses 8-pin)
