Yes, the new flash had the same issue. On a reboot the system failed to POST on a ram issue. Swapped ram with known working ram and all is well. Although I thought this ram was good, this is a silly lesson to learn. Don't assume hardware is working properly just because it was working at what time. Thankyou georgeb for your time.
Unraid won't boot after swapping from i7 3770 to 4770k, as well as swapping motherboard. Keep getting "end kernal panic - not syncing : attempted to kill init! Exit code 0x00000009 any help greatly appreciated
