Its usually powered up all the time and drawing its power from the UPS. One morning it was shut off, when i tried to power it up the fans starts to spin for half a second and then stops. The NAS had an identical motherboard earlier and was hit by a powerspike so it died (this was before the UPS). I have tried to switch powersupply but the same thing happens. I have tried to switch to the old motherboard but it was still dead. Could it be the motherboard this time again? If so, any ideas of why it could happen?
