Hi Sylvia,
1. I have tried the versions "553" and "559" to recover the BIOS. Unable to recover.
2. Since the board is not giving display, I am unsure about the current BIOS Version on the motherboard.
3. There is no model number mentioned on the processor, but I am pretty sure it is a Ivybridge-E processor.
(Motherboard Hardware revision # AA G28808-602)
4. I am using "Gigabyte" graphics card, Model # GV-NX62LTC256T
Regards,
