3100 locked up

[gherkin'd]

I say locked up, but my device is having performance issues.
After halting the system from a terminal session and pwr'ing down, then reboot; it seems to have gone wonky.
For awhile last PM (after mentioned reboot), the Dashboard showed 100% CPU and DHCP service not started.
So I again halted and pwr'd down for the night.
Today, I've performed file system consistency checks, reloaded Pfsense > rreloaded last known config.

This is a residential application self-bootstrapped on maintenance knowledge, so I'm not sure what else to say. But did capture the boot sequence and file consistency responses.
The 3100 has been running 24/7 since that last version update w/ that subsequent patch.

Any help and suggestions sure would be good, I'm afraid the hardware has failed somewhere.
