    AMD Ryzen Master locked my R5 1600 at 2 cores.

      Have a Ryzen 5 1600 and MSI B350 Tomahawk. Randomly overnight, 4 cores were disabled. In Ryzen Master it says Number Of Cores Disabled Lesser Than Current Cannot Be Applied.This Requires Power Cycle. So I quickly flipped on and off the power switch to cycle it. To no avail. Then I went into ms config and un-ticked a box in the boot advanced options screen, ensuring that I had 6 cores. Next I went into BIOS and made sure I had all 6 cores enabled, which I did. I've checked every forum post and YouTube video for people with this issue and tried every fix which did not work. I then made sure I have updated everything, bios version, and windows version. Need help quick as I have schoolwork to finish.
