HERE ARE A COUPLE SITES DESCRIBES CHASSIS INTRUDED.AND WHAT YOU POSSIBLE CAN DO ABOUT IT.READ IT CARFULY.

Hello, you can download a manual here:

http://www.asus.com/Motherboards/Intel_Socket_775/P5PEVM/#download

Please select your windows version.
Select manual and click on global for download.
Unzip the file before installation.

And remove the cable on the mainboard for the contact on the chassis.
When that is done enter the bios and set the setting for the chassis intruder to off
Read about that in the manual.
The chassis intruder is used by admins to see if the case have been opened
when the case is opened the bios will block the system from booting until the setting in the bios
is set back to normal.

Some computers will have a sensor to indicate that your chassis(case) is open. This sensor can get stuck sometimes and you will need to enter BIOS (setup) and reset it. You should be able to disable this feature in BIOS also and I would as it's not really useful other than having the chassis open and screw up the airflow and raise the temp of the computer internals.

Comment if you need further assistance

Good day! here's the following steps hope it will help you.

Unplug the computer
Take the MOBO battery out
Remove the chassis jumper
Wait a few minutes
Replace the chassis jumper
Replace the MOBO battery
Plug the computer in

okae...
first should you do is.. buy a new motherboard.. because like my motherboard, there is no solutions for that error nd problem...tnx

first you have to check the RAM,, then mother board or processor,, ,,, make sure the pc while booting memory check is going with out problem..s

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.

Cheers!

clear your bios, close very good your case, open bios disable chasisis open detected fro yes to no, (or in some model from enable to disable ) change saves exit booting and good work.

you need to go into the bios of your pc.....usually pressing the delete key when you see the first logo screen after booting up....look for a section that relates to errors and what the bios is supposed to do when it encounters an error.
i.e if you see a line in the bios that says "halt on all errors" disable it and when you next boot up the bios will not stall.

I'm not familiar with that particulat model, but I'd guess the motherboard has a chassis switch connector, and senses the chassis be open. Could be because: - chassis open (close it), - switch defect (as a workaround, you could short-circuit it, or just unplug it - whichever solution works for you). As another workaround, you can probably disable this switch in BIOS.
