RB450G missing Ethernet interfaces

hi,

I've had a RB450G running flawlessly for 3 years.
Suddenly this afternoon something happened while i was away - I can't say what it was (no pets in the house otherwwise empty)- all i know is that it took down one of my UPSes and the RB450G. I have multiple UPSes in that room, on different outlets, no problem.
When i switched on the UPS again, everything came back online properly, battery was at 100% charge - everything but the RB450G.
The RB450G booted up ok, interfaces started blinking but no traffic was actually going anywhere.
After plugging in the console and poking around, it looks like all the Ethernet interface information is gone.

[admin@router] /interface> ethernet print
Flags: X - disabled, R - running, S - slave

NAME MTU MAC-ADDRESS ARP MASTER-PORT SWITCH

[admin@router] /interface>

Anybody knows what's going on here ?

Thanks for the help,

Looks like all the PCI & IO info is gone as well -

[admin@router] /system resource io> print
PORT-RANGE OWNER
[admin@router] /system resource io>

[admin@router] /system resource pci> print

DEVICE VENDOR NAME IRQ

[admin@router] /system resource pci>

CPU load seems to be maxed out constantly - I’ve got nothing connected to it at the moment:

[admin@router] /system resource> print

Anybody from support can help ?
The board is still unusable.

thanks

What happens when you do a netinstall?
