First boot on brand new system (see bottom) resulted in the final message "Unknown CPU detected, updating BIOS is required to unleash its full power! New CPU installed! Please enter Setup to configure your system.
Fatal Error... System Halted."
(I do not have the chassis intrusion system connected, and the jumper is where it's supposed to be.)
I browsed the net for solutions to the "fatal error" problem, and I see that this is a problem many people experience with ASUS motherboards. The most common advice is to Clear RTC RAM, so I cleared the RTC RAM (CMOS) doing exactly as the manual says (removing power cord and MB battery, moving the jumper for 5-10 sec, putting the jumper back, reinstalling the battery, etc.).
After clearing the RTC RAM i am not able to boot the system at all. The PSU comes on when I press the power button, and the fans start spinning, but I get no picture, no beeps, no nothing.
What should I do know? Is the motherboard "dead"? Was it always bad, or was it wrong of me to clear the RTC RAM?
(All connections triple checked. The battery is in the right way and is full of juice, and the jumper is back to default. I have tried disconnecting all disks, front panel USB, etc. External connections: PS2 keyboard, DVI monitor, USB mouse.)
