HD 7970
ASRock z77 Extreme4

No, The mini speaker that is plugged in to the speaker port thing on the MOBO doesnt even make a beep.

The screen does nothing, it doesnt even matter if there screen is plugged in it still makes the same error
 
So make a minimum rig. Just one RAM module (you can cycle it in other slots and try the other module in the same way) at a time, CPU, Powersupply. All other devices, including keyboard, mouse, GPU, HDD, SSD, DVD and USB are disconnected.
If that doesn´t work remove all RAM modules.
After that Clear Cmos (read manual how to)

Can you post a picture of your Rig?

After multiple attempts to get video to show with the Extreme4 770, You may have a compatibility issue with the CPU. The mobo bio may be outdated with more recent CPU such as: Alot of the new FX series. To fix this you can hard boot the system mutiple times. (powering on and off about 5 time for me) then you will force the system to recognize your video output. Then update driver and d/l the most recent bio from Asrock.com. Also you will want to load defaults from the bios and possibly reset CMOS. That is how i got mine to work and it I have had no problem since them. I say all this after 5 days of trying to diagnosing problems with the HW. Also this is a solution after all basic diag have been complete such as loose memory, GPU, and all secure connections.

THANKS, Hope this helps someone.
