I just had two B250F boards, and now I'm using the Maximus VIII Hero.

All of these boards has the same issue!

1. BIOS Locks/Freezes Intermittently
2. Clicking on something lags - sometimes have to click several times to get something to respond.

I am using just plug and play USB2 supported mouse and keyboard, that does not use software drivers.

Mouse works fine under Linux and Windows, never any issues, these problems are exclusive to only the BIOS.

UI Stability needs fixing Asus...
