Find out AD computers that don't exist any longer?

Question

Dear experts,

In our on-prem AD env, we have quite a number of computers that are no longer used, meaning the computer objects showing up in our AD UI, they don't exist anymore. The most common scenario is that, some very old computers were decommissioned for asset control purpose so they won't be booted any longer, or some of the computers were renamed but the old names are still showing up in AD.

Anyway we can filter out these computers and take further action? Maybe Powershell or LDAP query or something else?
Thanks a lot.
