problem solved.
Send it to CDL. And the tech there re-flash the bios. Activate th 2nd bios. Flash everything and all is working great. Even a few mths off warranty he still fix it. Sometimes good after sales and customer service is important as good hardware.
Their tech has special tools or technology to flash a dead mobo?
I'm thinking of building a Hackintosh as well but don't have access to a Mac to make a Unibeast/Multibeast/Clover installation USB drive. Any way you can help with this?
My 3 yrs old gigabyte socket 1155 failed, when flashing to new bios. It's corrupted can't RMA cos warranty over by 4 mths, anyway to salvage it?
Any any store online or SLS sell any of these still? Or must buy a new mobo+chip combo?

You don't need Mac to make Bootable USB. You can run Mac inside VMware of windows PC, and create a Bootable disk
