My board is crazy:

It's new, arrived today, but when i power on, after the bios post:

Chassis Intruded !
Fatal Error... System Halted!

And i can't do anything, no access to the bios, nothing. I read the manual, but the Chassis Intrusion jumper is in default. Already claered cmos, but the same.

I don't now what to do.

Any ideas?

Sorry about my English.
