Перемычка нормально стоит под SATA разъемами? Выдержка из User

Chassis Intruder Connector: INTR
The connector connects to the chassis security
switch on the case. The system can detect
the chassis intrusion through the status of this
connector. If the connector has been closed
once, the system will send a message. To utilize
this function, set “Case Open Warning” to
“Enabled” in the “Power Management Setup”
section of the CMOS Setup. Save and exit, then
boot the operating system once to make sure
this function takes effect.
