Ryzen 5 2600 Throttling to 0.54 GHz on Cold Start

New PC Build a few weeks ago and my Ryzen 5 2600 processor is throttled to 0.54 GHz (0.768 V) when I first boot and it will stay that way until I restart. After I restart it is clocked to the normal 3.4 GHz (1.144 V). As far as I can tell there are no temperature issues because it is idling as it was just booted and it doesn't go above 30C. I've been checking and updating drivers and BIOS without any success fixing this issue. I checked the windows 10 power plan and it is on high performance. I uninstalled some different monitoring/overclocking softwares, thinking some of that may be causing it but still no fixes. Do you have any ideas?

Here are my specs:
CPU: Ryzen 5 2600
Mobo: MSI X370 Gaming Pro Carbon

RAM: G.Skill Ripjaws V 2x8 GB DDR4-3200 (A-XMP Profile 2 for 3200 MHz)

Storage1: Samsung 860 Evo 1TB
Storage2: WD Caviar Blue 1 TB 3.5"

GPU: EVGA GTX 170

PSU: Corsair RMx 650W

I found a fix if you have not yet RMA'd however it may still be worth RMA'ing.

Download Ryzen Master.
Open Ryzen Master and go to Profile 1, and put it into Manual Mode.
Open the Settings and disable PROCHOT.
Your CPU will stop throttling, but this also means nothing will throttle it if it gets too hot.
What this suggests to me is that maybe the motherboard is detecting a false reading of being too hot and the CPU throttles.

But this works, while you're in Profile 1 after disabling PROCHOT, click "Copy Current" in the bottom left and save the profile.
