Probably not the BIOS, but give Swicks Bios a shot. If that doesn't do it my GUESS maybe a monitor going out? at least the controller. 

 

Did you have windows 10 installed by chance? If so you might be one of the victims of the dead monitor conspiracy. I believe Mr. Fox found a fix, but it requires direct reprogramming of the Display controller with special hardware.

 

Again just guessing trying to help. Sorry if i waste your time. I'm sorry to see that beast of a machine having troubles. and GOOD luck man!

 

Also... I was going to ask if your CPU was overheating and shutting down, but you said that it works on external just fine.

hmm. Feeling like it's the display controller for sure.
