I don't think JKR has an established canon about how ghosts interact with electronics, since wizards tend to avoid them, and it's not super relevant for this era anyway... but I personally love ghost-lore where they can manipulate things that run on electricity so for the sake of this I'm rolling with it.

Modern AU Ford and Barnaby Wye play Xbox games together. Barnaby cheats by making the screen glitch any time it looks like Ford might win. When Ford tries to call him on it Barnaby tells him it's clearly a problem with the game and he should try taking the cartridge out and blowing on it and Ford is like "games haven't worked like that in fifty years barnaby."

There's also a rule that the Xbox can never be left on idling because Barnaby is only allowed to use it with supervision. Otherwise he gets in fights with random Muggles via online gaming.
