The first rule of beta is: "If it was working and now it isn't....what changed?"
hooked it all back up with a new video monitor
This makes me ask: did you try booting with the old monitor? I don't see anything in your troubleshooting that suggests you tried this.
Beyond the monitor, you say you moved it two feet. Not much can shift internally (provided you did it carefully). It's the stuff on the outside more likely to have been stressed. This suggests the classic reseating the BFC and strain relieving the cable to the console....and possibly reseating the desk's internal ribbon connectors. I'd try the BFC first.
