BIOS Error B4

Hello,

 

Yesterday I finished building my first PC (Biostar X370GTN + Ryzen 1600) and it has been working great so far. Even after restarting a few times.

 

However, today I tried to start it up and it showed in the corner of the BIOS boot screen "B4", which I assume is an error. It hang there for a few minutes and I decided to reboot the PC and it loaded Windows just fine. I'd like to sort this problem out before it becomes something serious though. Is it normal?

 

The only thing I did differently today is that I turned on the surge protector power strip with the cable that goes into the PSU (which was already ON). When I did that, I noticed that my mouse wheel, which is backlit, turned on for a fraction of a second. I have no way to plug the PC into a socket with the PSU turned off as the Node 202 has an extension that runs from the PSU to another socket, and you cannot access the PSU back-panel.

 

Any idea on what happened? Should I be worried?

I guess derpy memory, update the BIOS to the latest version, might solve it.

If you want my attention, quote meh! D: or just stick an @samcool55 in your post :3

BIOS is already updated to the latest version.

Do you maybe know if the BIOS uses AGESA 1.0.0.6? If it isn't, turn down the memory speed a bit until you have a new BIOS with the new AGESA.

BIOS is AGESA 1.0.0.4. The memory is running at 3200MHz, but that memory is known to be reaching those speeds also with the initial BIOS.

EDIT: I read online that B4 is USB hotplug error. It seems strange that the system booted fine even though I kept everything plugged in.
