Question My PC always go to bios when my keyboard is plugged in

[aditiya_39]

When i turn on the pc, it will always go to bios, then i need to choose disk manually to boot to my OS
But this only happen when my keyboard is plugged in

When i try to remove the keyboard, all works fine without issue

All button on my keyboard was fine, Del button also not a problem (del was key to go to the bios)

Is PC a custom made one of Brand name?
If custom, what motherboard?
If brand name, what make/model?

have you tried different USB slots?
