Try to configure the GPU and CPU and see if it helps. I read a couple of websites it could be hardware problems like bad memory or monitor cable or a configuration problem.
If your motherboard is a MSI B350 Tomahawk, there are very new Updates for the BIOS and Chipset:
BIOS - 7A34v1G - 03/20/2018
AMD Chipset Driver - 03/28/2018
*** Be warned, many Users are having problems when Updating BIOS on MSI B350 Motherboards. Sometimes after BIOS Update, the computer won't POST.****
