Install the latest BIOS again, but this time do so via the recovery method....
The recovery method is the setting where the jumper is completely removed? If so, I have tried this a couple of times with no luck.
I've even tried downgrading to v104 and the same problem.
Ok, next, check if, despite the fact that nothing being displayed, you can press F9 and have it do a restore defaults operation.
So, not sure how, but the only thing I can think of was I reseated all connections to the motherboard, and suddenly my BIOS works again ..
I can't think of anything else that happened along the way.
Thank you for joining the Intel communities.
At this point I suggest clearing the CMOS, removing the battery from the motherboard and any other component connected to the motherboard for at least one hour and try the BIOS recovery again.
