"Chassis intruded" pre-BIOS error on boot. P5K (SOLVED)

EDIT: Since my first post, I have fixed my issue. Hope the checklist of solutions below proves useful to others suffering the dreaded Asus 'Chassis intruded' error.

Be sure to refer to an approved guide and/or online manual for each of these fixes.

(For me, it was a simple hardware connection issue, Fix 2. Guess my soundcard was a little loose. Duh.)


----------------------------------------

As always, thank you in advance guys.

Tearing my hair out here.

The story: I recently cleaned and dusted my whole rig.

But now, after careful reassemble, I get a 'Chassis Intruded' error every time I try to start up.

The only change in my setup are two additional fans I have installed.


I have scoured for solutions to the Asus 'Chassis Intruded' and have tried the following:

Fix 1 - Reset CMOS:

1. Power down, unplug, remove MOBO battery

2. switch jumper pins from 1-2 to 2-3 for 20 secs

3. return jumper pins to default position

4. Boot.

(This method allows me to boot up ONCE, as it reverts to a 'BIOS setup' default. As soon as I shut down then next time, same problem. Please note, I can't access BIOS before the message appears. Also, there is definitely no option to permanently bypass the Chassis Intrusion feature on the Asus P5K Premium. Thanks a bunch, Asus.)

Fix 2 - Check for loose connections/wires touching case. Check for loose screws. Check case is secure.

Fix 3 - Bad RAM? Try with one stick. No good. Try another. Still no good.

Fix 4 - Flash BIOS to latest version with EZ Flash update utility. Update succesful. Boots once, as above

Fix 5 - Reset 5 times in a row.

Fix 6 - Check Chassis Intrusion jumper is secure

Any ideas, folks?

just googled your problem. Do a cmos reset and enter the bios. There should be an option to disable it in there.

However, here's a direct quote from a post someone made over at TomsHardware:

"This is a fun one. Some motherboards need the header to be jumped for it to work there might never be a setting in the bios for a chassis intrusion. Heres what you do...

Get a jumper there might be an extra one some were in your box or with a old hard drive or go to the store and pick one up

locate the header for chassis intrusion and put the jumper on it.

Check your manual for the location of the header or look at the headers on the motherboard usually makers of motherboards abbreviate the labels under or near them.

Like i said again there might not be a setting in the cmos i have seen that happen on asus / abit motherboards. "

Should fix your problem.

Thanks for the fast response, but as stated I have tried those fixes.

Ahh right. I saw you mentioned jumpers, but i didn't know for sure which ones you meant. Sorry about that.
 
This will sound rather silly, but have you tried pulling the ATX and AUX power plugs from the board before resetting the CMOS?

The power supply has capacitors, and those capacitors store power. On older BX Intel boards (P2 slot 1) if the board got any kind of upset you needed to pull the power plug and let the capacitors on the board itself run flat.

There's just one thing worrying me here. What did you clean and dust your rig with?

We had a big discussion about this the other week you see.

Also this. Fatal Error would have me rather worried roundabout now. I have a really bad feeling you have Donald Ducked your motherboard when cleaning.
 
Hi guys, thanks again.

Killablade: I cleaned the motherboard using and air duster, and to a lesser extent a lint free cloth dampened with isopropyl alcohol.

Hi AlienALX. Im not familiar with ATX/AUX: But I removed the main auxillary power plug - not the internal one that plugs into the mobo. I will definitely give this a try.

Great care was taken, but it's always possible that I screwed it somehow.

Definitely running out of options, aren't I?

Damn.
 
Having said that... Doesn't the fact that it boots perfectly well off a CMOS reset (but not after that) indicate that it is perhaps a more minor problem?

Gah, who the hell knows. So tired of this! Just want to play my beloved games..

What it suggests to me is a fried CMOS chip. Or something broken somewhere (a short from the sound of it). Check out the second mobo I linked you to. Poific. Nuff'n special but has everything you need.

EDIT. GOD DAMMIT. I wish Scan would remove out of stock items.. I shall continue my search.
 
I appreciate that, man. I'll order one tomorrow if I have no success with the 'total' unplug CMOS reset.

Perhaps this is another thread- but given my specs, and the fact I am keen to OC, what is a decent mobo for up to £60/100USD?

Wifi is not a requirement, and I won't be making use of any features that incorporate hardware I don't already own.

Edit: Cool, thanks pal, I'll check that out!
 
Ah ok. I'll see what else I can dig up :) TBH with a 4870x2 you can't really crossfire it and expect it to work any way, so a micro ATX with 4 DIMM slots and a 16x PCIE slot will do you well.
 
Cool, ok! I'm crashing out now but will check out your research when I get up after giving the P5K one last try.

On the plus side, the airflow situation is extremely sweet and the rig looks wicked- I'll post some pics to show what I was going on about last time :)

edit: thanks killablade, I'll check that out tomorrow too!
 
Backflips! BACKFLIPS, I say!!

OK guys, seems I found the problem in the first thing I tried this morning. (isn't that always the way?)

1. I tried booting with the soundcard (XFI xtremegamer) unplugged. Success. Feared for toasted card.

2. Turned off, Taped back a few unused stray looking wires previously lurking near soundcard, and plugged it back in securely. Booted. Success! :D

Still a little terrified it will revert, but 10 resets so far and still no dreaded Chassis Intruded error.

PHEW!

I would be lost without you guys *wipes away tear*, thanks for your help and advice.

I'll add the fix "check hardware connections to mobo" to my first post. Hopefully it will help someone else with an Asus mobo suffering from these issues.

Now all I need to do is learn how to OC. Shouldn't take me more than 10 mins, right? ;)
