Hey all, I just bought a new cpu, upgrading to a Ryzen 3600 from a 1400, and to do so I needed to flash my bios to a new version. Well I followed all instructions, and went into the bios, selected M flash and it asked if I wanted to boot it into flash mode, I said yes, and it restarted automatically and went to a black screen.
It didn't ask me to select my flash drive or my bios file. Just restarted and went to a black screen. I waited about 10 minutes before restarting and I'm still on a black screen. I've tried resetting CMOS battery but it didn't help. Any suggestions? My mother board is the B350M Bazooka.
