Sudden bd error

[ynlexposure]

i7 5820 on Rampage V Extreme 2011-v3 with HyperXFury32 GB. Ran great for nearly two years then suddenly stops booting with MB error code bd. Monitors receive no signal at all. How should I proceed? MB, RAM or ??

Thanks community!

Finally got the the computer to boot to Bios by clearing cmos. Only 3 of 4 ram sticks were shown installed. Swapped DIMM slots to ensure ram was problem. It was! Running on 2 for now. Contacted Kingston who will replace all 4 sticks at no charge. HyperX had 5 year warranty and these are only 21 months old. ASUS support walked me through their troubleshooting, great help.
