AMI BIOS "Fatal error ... System halted" on Asus Mainboard

By tobs ·
I have a new mainboard (P5GD1). But I cannot boot nor can I enter BIOS setup.

The computer starts and all IDE drives are recognized.

Then, right after "Chassis intrusion detected" the message appears:

"Fatal error ... System halted". All I can do then is reset.

No further explanation, no POST beep codes - nothing.
Has someone experienced this behaviour before? Any ideas?
My guess is that the MB is gone.

Have you tried clearing the CMOS?

From the symptoms, I can't conclude that the motherboard is toast at this point.

The BIOS may be corrupt.

The CPU or RAM may be bad.

Could even be a fan RPM monitor issue.

As Chas said, could be any number of causes.

Since BIOS memory and CPU tests are performed prior to drive identification, memory and CPU are not likely causes, although cannot rule them out completely.

The first thing to do when troubleshooting is to reduce your system to the fewest components necessary for a basic boot. Disconnect signal and power cables from all drives. Remove all add-in cards except video card. Disconnect any other peripheral devices (i.e. printers, scanners, USB drives).

Remove motherboard from case and place on cardboard or foam to rule out chassis shorting.

Try to boot with minimal configuration. If successful, sequence back removed components until the culprit is identified.

If you still cannot boot, posibilities have been narrowed down. Try these first and post back with results.

1. Ensure CPU cooler fan is operable.
2. Reset BIOS.

Anytime I build a new system or replace a mobo, I assemble mobo, CPU, RAM, and video; hook up a power supply and keyboard; and boot motherboard on bench prior to mounting in case. Catches problems quicker while everything is easily accessible and makes identifying shorting/grounding problems after assembly in case easier.

Will,

I followed your suggestion. Now its taking me as far as detecting the USB storage but it stops there.

I get "CMOS settings wrong! Overclocking failed! Chassis intruded!" and the dreaded "Fatal Error...System Halted".

Problem now is I cant enter setup. Its says press on <Delete> while booting which I did but to no avail.
