Re: The second-hand computer I bought can't play apex
sorry to hear what happened to you.
From your title and description it looks like the used computer you bought has a hardware ban on it.
Here on the forum we can not help with bans and such outside of some tips.
You probably need to contact the seller for a refund if possible.
You might be able to contact the ToS team and or and EA advisor in order to explain the situation.
This is one of the reasons I would never buy a used console x-box PS4 switch etc. as for a used computer it is even more so as there could be many other things wrong with the PC and or hidden software installed.
I wish you the best of luck with your issue though.
