Weird boot issue

[Foga]

Hey,

 

I upgraded my R5 2600 Asus B450 prime combo to a R9 3900x Msi x570-a pro combo 2 days ago. The system worked just fine. A couple hours ago I went away for an hour and the pc seemed to have died in the meantime. When I tried booting it the system fans would spin for a split second and that was it. So I started troubleshooting and found out the PC booted without the CPU power cable plugged in, I then tried with the R5 2600 in the new motherboard and had the same issue. So it can't be the cpu. Then I tried the old motherboard again with the old cpu and that booted fine so it can't be the power supply. So it has to be a dead motherboard right? Anyone know if it can possibly be something else?

Have your tried updating the motherboard BIOS? If not, you might want to try it.

Am I able to do that without the cpu power connected? It won't boot otherwise.

According to MSI, it seems like your board does not support BIOS flashing without CPU. So, you need to connect your CPU power cables.

As for flashing the BIOS without able to enter the BIOS settings, your board have a flash BIOS button on the back.
