Hello, I'm new to the board, but this looked like the place to go for answers.

I recently bought a new case, and unlike my old one, it has a chassis intrusion cable (black and white wiring with a button on the case). My question is, what does it do? I am sure I haven't touched it, but now my computer only boots to the bios, and I get an error message saying the chassis has been intruded... or something similar.

There is a connector on the mobo called 'chassis' but none of this is detailed in my motherboards manual.

Thanks in advance

Hi there

The chassis instrusion connector on the case connects to the motherboard (in your case, it sounds like the 'chassis' header you referred to, but not all mobos have one).
Basically it connects to a physical switch (or button) of some type located on the chassis. This switch is pressed down in normal use but when the side is removed (ie when the case is opened up) this switch is released. This breaks a circuit & tells the motherboard that the case has been opened up.

Next time you power the machine on, even though the case may be reassembled at this point, you will receive a warning from the bios, informing you that the case has been opened up.

The point of the chassis instrusion switch, is basically to alert you to potential unauthorised access to your machine (ie if someone other than you has been inside the machine without your knowledge etc)
