CHASSIS INTRUDED My CPU was grounded. I removed it from the casing and placed a insulated cushion underneath the board. When I placed it back and connected all the peripherals. It showed a CHASSIS INTRUDED! error. I just pressed F1 to continue and it turns off at an average of 5mins more or less. Can anybody please help.

You BIOS settings have been reset and you need to set it up again. Chassis intrusion needs to be turned off. You can download the user setup manual here: BIOS setup is in Chapter 2. There are alot of settings and it goes into detail on how to set them. This is truly an Awesome motherboard! I wish mine was like this. Follow the setup carefully and you can't go wrong.

Hi, have you got this board installed in a case, with all the connections made? Usually there's a two pin connector to a microswitch that detects if the case is open. If you can identify that on the board you can short the switch, fooling the system into thinking the case is closed, to get inot the bios etc.

"the system intruded chassis opnened

The NRL_LS has a connector for a microswitch on the case, to detect if the case is opened.
Look for jumper J2, between the battery and the bios chip, at one end of a long connector CON1.
There should be 2 adjacent bare pins at one end of J2.
Place a jumper block on them, and the system should start normally.

The manual is here +NRL-LS Cover.P65 -

Look at item 9 on page 2-22, referring to jumper J2

My P4B will not boot. I am trying to install XP and all that comes up is "system intruded chassis opened or tampered before. Please check system. The installation is A-OK. what do I do. PLEASE!! Paul

This board has an Intruder protection sensor - practically it's a pair of pins (bottom right of the board) with a strap that when removed signals that the case has been opened. Put the strap back and it will be OK.

Cpu chassis intruded? can't continue installing windows

You can go to ASUS and find the pin out for your unit.
Or you will have to look hard at the board and find a open set of contact pin for a lid switch.

How to fix chassis intruded ..fatal error..system it my cpu become damage?

It is unlikely that your CPU is damaged

You need to enter the BIOS and turn off chassis intrusion.

It is an option in the bios that is only useful if you have the switch on the computer case that supports it otherwise it will give you the error you see if enabled

Chassis intrusion

You need to check the chassis intrusion pin setting located on the motherboard. See page 1-30 (Number 11) in your manual.
You need to add a jumper as shown.
The system should no longer halt.

System failed cpu test

I think the problem is the mounting screw of the motherboard to the casing is grounded. You need to put some plastic insulator to the metal screw to avoid the grounded in the board.
