Hello,

For 2 days now, my 4-year-old Asus motherboard shows this error on boot:

Chassis intruded!

Fatal error…System Halted

I do not know what seems to be the problem. Is my motherboard going bad?

Could it be one of the attached devices?

I need help. Thank you in advance for any suggestions.

Hello Ethan.

Some motherboards have a feature for detecting when the CPU chassis has been opened. 

That feature is used for CPU chassis that have chassis intrusion switch such as the one shown below:

.

  • You didn't say whether you have a chassis intrusion switch or not.  If you do have a chassis intrusion switch and you have it connected to your motherboard, you will have to reset it.  The tutorial on this site will explain how to reset the switch.
  • On the other hand, if you never had an intrusion switch installed in the first place, then you should disable it in the BIOS options.  See your motherboard manual for details on how to do that.

  • The error here is right inside your BIOS setup. The Intrusion Detection of your BIOS is enabled that’s why you are seeing this error during POST (Power-On Self-Test). This security feature enables the opening of the casing of the CPU to be detected and thus an alert during boot up is expected to be displayed. The action of the alert depends on the option selected in the Intrusion Detection’s setup.
  • Go to your BIOS setup by pressing the DEL key on the keyboard. Once inside the BIOS look for the section there where you can find the security feature of your board then find the one that says Intrusion Detection. Set this to Disable.
  • This security feature of the board ensures the integrity of the devices attached inside the CPU and will alert you if somebody tried to open it. This is a good feature and I think most boards has it. But if you are not familiar with this, just disable it so you will not have any problems.
