No Display When Powering On Computer. Beep Code [1long,2short]

Where are you sticking the cable to the motherboard and not gpu? Is this the board listed in your specs on here because that has no onboard video on it and you must use a add-in gpu. If your VBIOS is messed up on the 970 it might be rma time.

So the VBIOS error is when your using the onboard then, Try running with only one stick of ram in the slot closest to the cpu. If that does nothing try removing the other gpu from the motherboard then try the onboard after leaving the cmos battery out for like 5 minutes to make sure everything is cleared?

Okay now comes the time consuming part as you really should test each stick individually with memtestx86 + and if they all pass in the first slot then try the second slot to determine if you memory slots have gone bad or the sticks themselves.
RAM - Test with Memtest86+

EDIT: If you find bad sticks test the good one in the other slots to make sure the slots are still good.

So they are in a row of 3 minus the first slot?

Did they used to be together cause if they where you don't get dual channel and it's probably why it did not boot. Always gap it as they go in pairs like white/blue, white/blue.
