Hi, Everyone

I have a dell inspiron 5348. I recently changed the motherboard. I was having a bootup problem. I changed the motherboard to "Dell Optiplex 9030 AIO All-In-One CYTN6 LGA1150 Motherboard" the problem I am having is the message I keep getting "Alert! Cover was previously removed".

the computer works fine after the motherboard replacement.

Things I have tried:

Reset the motherboard ( jumper/ remove coin battery)

reset the bios to default

cleared the error log in bios

looked for Chassis Intrusion on the System Security screen, unable to find the option.
