PC Won't boot, stuck on Error b2 of Asus Maximus VII Hero

[EgoRiot]

I just built my rig last night and its my first time building. I had some errors before but I solved them over time. However now when I boot up the computer the motherboard gets stuck on error b2 of the Asus Maximus VII series.
My rig:
I7-4790k
Asus Maximus VII Hero
Corsair Vengeance 2x4gb
MSi GTX 970 4GB
EvGA 80+ 650W PSU
Cooler Master Hyper 212 EVO
TP-Link N900

I have looked at solutions on the internet and have tried switching the ram from red to black slots, but the error persists.

Sounds like video card or PCIe slot on the mobo. Do you have any other parts to test with?

Make sure your mobo's BIOS is up to date. Perhaps the card BIOS need updating as well.

I haven't tried to boot the bios yet, I just removed the Pci-e wireless networking card and will see if it makes a difference. everything turns on and runs as I see the gpu fans start up but then stop as the error code shows up on the motherboard

Can you boot on the onboard graphics?

I figure it out, one of the pins to the PSU had gotten loose and when I reconnected it it started working again. Thanks again!
