Question Sudden problem with Radeon R9 280x BIOS?

[Zhero]

Hello.
I'm having a problem with a Radeon R9 280x Vapor-X card. Yesterday my hackintosh rebooted suddenly and now, when I start the PC I see the graphic's card BIOS screen instead of the Gigabyte Motherboard BIOS. See the attached picture.
If I disconnect the card and use the onboard graphics card the system boots ok and I see the correct motherboard BIOS screen.
Could it be a problem with the bios card? I even tryed with "second bios" button of this ATI card but nothing changed.

Now I'm looking to re write bios rom on the card. Any advices?

Thank you all.

It seems that your 280x has some memory chip malfunction. So it's pretty much dead, for band-aid fix some heat threat might bring it back to life.
