AMD Ryzen 5 1500 in Asus B350F mobo crashing after 4-5 minutes of being in windows. Black screen, default fan settings, power button on IO does not function. Have to hard power-down wit PSU toggle. I ran Memtest86, no errors. I am not overclocking, all temps look okay. Any ideas? My Ram is ddr4 3000, but my set freq is 2666 bc this mobo can over handle 2666 w/o overclocking. I am left thinking it is either an OS bug (windows 10 pro), or something wrong with mobo. My PSU is only a 550w, but i dont think its having a hard time keeping up. Gpu is asus rx580 8gb. Help! No clue whats wrong!
