Ender 3 Z axis not moving

Your board may certainly be at fault, but the stepper drivers that are hard-soldered to the board are the more likely trouble. Unfortunately, one doesn't pull them out and plug a new set in place. You may want to consider contacting the dealer from whom you purchased the printer to see if you can get a replacement board under warranty.
