C6 Q code no boot need help

[Nitwhitt]

If anyone can help have a asus crosshair viii hero motherboard with ryzen 5 5600x been running flawlessly for 6 months and out of nowhere computer reset on its own and now shows c6 Q code dram fault light on and will not boot at all. Tried 6 different known good sticks of memory one at a time and no change. Flashed bios reset cmos and no change. Any help would be much appreciate

try reseating the CPU.  could be a pin not making a connection anymore.  take the cooler off clean the old paste off.  remove the CPU.  Reinsert the CPU apply new paste (get some before you do this if you don't have any) reattach the cooler and try again.  if it's doing it with known good ram it's a CPU issue.  COULD be a board issue.  but id say it 90% likely to be CPU.  Do the steps and come back let us know if it changes
