Your manual will *CLEARLY EXPLAIN" each location what each connection, port or headers(connections) are at. It's there, just read and review it, don't guess. The manual must be on the install disc, so access it and print what you need from another PC.
You need to use the "clear CMOS" pins to return the bios back to defaults and it should clear the current error status. If done properly and reading the manual, set the "intruder setting" to none or disable. if there actually is some jumper, again from reading manual, do the same. You can remove the CMOS battery if desktop model PC for 5min. and return it for same result of clearing CMOS pins.
You're going to have to do the above before you can proceed. Don't assume anything, know what's what before you make a serious newbie mistake; take your time and care, then do what is required.
Hi I just recently built a new pc and when I turned it on for the first time it went into the bios and posted, then I plugged in a DVD drive to install windows and it restarted my PC and booted up saying Chassis intrude! Fatal Error... System Halted. I don't really know how to fix it but I have heard that you need to disable it through the BIOS which I can't access at this point. And I also can't find anything labeled with the 3-pin connector for the Chassis the closes I could find was something labeled GND USB1+ USB1- VCC but still it doesn't work for it.
My system is running this listed parts:
Intel Core i5 4670K 3.40GHz
8GB of ram DRR3 1600Mhz
ASUS B85M-E/CSM Motherboard
Thermaltake Commander MS-1 Snow Edition
Cooler Master Extreme Power Plus 600W Power Supply
2TB WD Hard Drive
SanDisk 64GB SSD
