If I read your question right, what you want to know is why the motherboard alarm does not work if you remove the CPU, memory or display card.

I’m not sure which alarm you are refering to. If you mean the BIOS option for open case alarm, the case itself has to have a latch which supports BIOS open case alarm.

Without looking up that specific motherbaord, I’d suspect there’s one of those annoying “voice alarm” settings in the BIOS that plays errors via the main speakers if present. If so, disable it and see what you get. I’ve found those “voice errors” very unreliable on most boards.

That board has a chassis intrusion sensor. It’s not supposed to sound an alarm when you pull a card out of a slot.
