Im lost, I bought some upgrades for my wifes computer. Assembled everything new CPU, RAM, NVME m.2, and old ssd. powered on, got RGB everywhere, no post from gpu, or igpu. tried flashing the bios and still same issue, no post at all. Returned that mobo thinking it was defective. got replacement and before installing everything tried mobo only. no post, added cpu, no post. still get rgb and cpu debug light, (no ram debug, even though ram is not installed).
AMD ryzen 5 5600G
MSI b450 pro carbon max wifi
2x 16gb corsair 3000mhz vengence RGB pro
samsung 970 evo plus 500gb
corsair cx550m power supply.
display connected via hdmi (works just fine on other pc)
mobo has 2 cpu power connectors 8pin and cpu2 4pin.
power supply has a 4+4 connector, tried both as 8pin and as 4pin.
both ways i get rgb but NO POST.
I should be able to get a post some way. I havent tried much since the 2nd board has done the same as the first.
