Many years ago I was involved with a large and very expensive electronic test machine that failed to work correctly for many months after it was moved to a new area.
Bizarre symptoms: Erratic random behavour - somtimes, lights suddenly coming on and flashing. Computer rebooting. We swapped many modules which seemed to cure it until it happened again the next day!
Cutting a long, long story short, the tech who did the move mixed up neutral and earth (this was in Europe with a US Blck/White/Green equipment wiring to a big (Hubble??) connector.
In short (bad pun!), although Neutral and Earth are connected back at the breaker, all kinds of wrong currents were lifting the chassis level. With 5v logic it doesn't take much ground crap noise to wreak havoc!
Just a thought - get somene to check neutral/earth integrity. You can't do it yuorself.
