Guys, my 390 suddenly went down yesterday with a blinking amber light. I searched these forums and guessed it's the PSU, but I'm seeing the same thing with the new PSU.
Is it the motherboard then or could you help diagnose a bit further? Few observations:
I'd appreciate any help you can give!
That sure sounds like the motherboard is bad, since the PSU is good and there isn't anything else.
Thanks, that's what I figured as well. I've ordered a new board, will see if that fixes the problem.
Turns out it WAS the MB. Replaced it and all is good. For others in the same situation, I had a RAID 5 setup and was worried I might lose the data if I connected the disks into the wrong ports. Looks like you can always replug as necessary if the system doesn't recognize the RAID - just be careful not to get into the RAID configuration at startup (Ctrl+I) and do anything there that'll regret.
