[SOLVED] MSI MAG B550M MORTAR WIFI - FLASH BIOS

[James - New PC]

Hello folks,

in February 2021 I bought MSI MAG B550M MORTAR WIFI motherboard which I intend to use with a brand new AMD RYZEN 5 5600X CPU and I am struggling with bios flashing (with no CPU installed). I do everyting according to the MSI manual, but when I push the flash bios button on the back of the board, nothing happens. No LEDs, no PSU activity. As of PSU, I am using Cooler Master MWE GOLD 750 Full Modular. It seems there might be some problem with the PSU, since the motherboard is not responding at all. Does anyone have similar problems? And what are your suggestions to fix this?

Thanks!

James
