AsRock h81 Pro BTC 2.0 New Bios? 1.3?

Hello I just got the above mentioned board, to add my 3 graphics cards to the system. Setup listed below, I have had quite a bit of problems since starting, when no GPU's are installed I got windows 10 working and updated. However when I start to add GPU's the fun begins, I notice the HDD i was using was working hard to do ...well anything, so tried another same thing, so found out those two were shot. So finally got a good drive, but on all previous setups either 1 GPU would not show, or another. At first it was the Zotac 1070, now it is the 980 Ti, so I uninstall drivers and reinstalled. The problem switched to a different card, without me swap cables or risers. No when I try to install Nvidia Drivers it will hang, freeze, black blank screen. I have switched PCIe Gen AUTO to Gen1 but not Gen 2 yet. Will try when I get home, but unable to install GPU drivers, and when I did the computer froze. I read on some forums where someone on reddit said that Asrock sent them a beta bios 1.3 for this board, is this True? Is it a scam, fraud, or something stupid? I thought this board was already optimized for plug and play, so why is so many people having trouble with connecting hardware, and going?
